SE8A is the first power delivery controller with embedded Secure Element for added protection against unauthorized chargers The new chips support up to 100W-charging and meets latest USB-PD 3.0 specifications.
Samsung Electronics, a world leader in advanced semiconductor technology, today announced two USB Type-C power delivery (PD) controllers, SE8A and MM101. With the new PD controllers, power chargers are able to communicate with the device to deliver the optimum amount of power for more efficient charging through authorized products.
Both chips are built with an embedded Flash (eFlash) that allows the flexibility of modifying its firmware to meet the most up-to-date specifications and are able to supply up to 100 watts (W, 20V / 5A). SE8A is the first PD controller in the industry to embed Secure Element, adding an extra layer of security to PD controllers.
The new PD controllers meet the most recent USB specifications for fast-charging, USB-PD 3.0, that addresses the compatibility and efficiency challenges across different mobile devices as well as other electronics. Such challenges can cause the device to charge slower than usual or excessively than required that can also compromise the lifecycle of the battery. With the growing need to extend always-on experiences quickly and as more devices adopt USB interfaces for charging and data transmission, efficient and secure fast-charging technologies are expected to benefit consumers through a wide range of applications.
“In addition to smarter features and larger batteries, innovative charging solutions allow us to do more through our mobile devices today. Following this trend, power adapters that can quickly charge devices while establishing safeguards against unauthorized access are increasingly in demand,” said Ben K. Hur, senior vice president of System LSI marketing at Samsung Electronics. “Samsung’s power delivery MM101 and security-enhanced SE8A will not only make charging faster and safer but also enable new services that can enrich tomorrow’s mobile experiences.”
The MM101 supports a symmetric encryption algorithm, Advanced Encryption Standard (AES), for product authentication and includes moisture sensing capabilities to ensure safer charging conditions.
Samsung’s SE8A is the industry’s first solution that combines a PD controller and Secure Element (CC EAL5+ equivalent) in a single chip, providing extra measures of protection such as security key storage, and encoding and decoding of sensitive data within a device in a compact form factor. The SE8A supports USB Type-C Authentication, a certificate-based authentication program for USB Type-C chargers and devices that prevents the misuse of unapproved products. With enhanced security, the SE8A opens possibilities for new kinds of content and services that may be exclusive to a certain brand, location or event.
By supporting up to a 100W capacity, compared to the general smartphone charger’s 10W, power chargers with Samsung’s PD controllers can be used for a variety of devices other than smartphones such as tablets, laptops and monitors.
For additional safety, both chips also provide over-voltage protection. The MM101 is currently sampling and the SE8A is in mass production.

Power-module designs require high power density, excep-tional thermal performance and a full feature set in order to be competitive. One way that power-module designs can meet these needs is with buck controllers with exter-nal metal-oxide-semiconductor field-effect transistors (MOSFETs) in their power architecture. Buck controllers with external MOSFETs allow current scalability and provide superior thermal spacing—both are key items in power-module designs. In this article, the operation of the DC/DC buck controller with external MOSFETs is compared to converter solutions with integrated MOSFETs.
External MOSFET considerations
Because converters have integrated MOSFETs, designs are restricted to the MOSFETs chosen by the converter manufacturer. Power modules designed with buck controllers and external MOSFETs provide the flexibility to choose the MOSFETs used in the design, which can provide advantages for pricing, sourcing and current-scaling. First and foremost, however, is the flexibility to size the control FET and synchronous FET for optimal efficiency and thermal management.

The DPS5020 is a constant voltage/current programmable control power supply module, that integrates analog and digital control in one device. Th e module is a 0-50V/0-20A Lab PSU module that comes in 2 parts, the main controller and a front panel. The main board has connections for input/output voltage as well as connection headers for Bluetooth and USB to Serial converter.
DPS5020 in the box
The front panel module has buttons and a control knob to set the desired voltage/current and an OLED display to show actual readings and set points. The DPS5020 can store up to 10 preset group values which are preserved during power off. You can also quickly set two stored group values. In comparison with traditional analog power supplies, it is more convenient to quickly set the voltage or current required. Using the provided instructions, assembling and switching on the device is straight forward. Along with the package, you will receive a small user manual, cables, and the two main modules.
DPS5020 Unboxing
USB and Bluetooth Connection
In the box, there’s is also a FTDI – i.e. UART to USB converter and a Bluetooth module (with pass: 1234, which just looks like a wireless UART COM port). You can use the available software to make a serial connection (wired or wireless) to the module, by downloading the PC software accordingly. Once the software is loaded, and the serial connector is connected to the board and PC, you are able to control the board from the onscreen menus. When the maximum current is set to 1A, voltage is set to 5V and connect a 2-ohm load, the voltage immediately drops to ensure no more than 1A flows through the load. This is the current limiting feature.
When the current limit is removed, the same load draws 2.4A and that’s a total of 12w of power, which follows Ohms Law. In this case the output voltage stays rock solid at 5v and the supply itself remains cold enough. To test another scenario, you can set the output to 20mA, attach a small LED to the output – and turn the unit on.
DPS5020 front panel module
User Interface
The photo above shows the HMI in use. The Green/Yellow/Purple text in the middle indicates actual output. On the bottom (cyan), you see voltage in, on top (cyan) you see Voltage and Current setting. You can notice that Voltage reading shows actual output voltage, not the set point. It is possible you will actually see a +/- 0.01 offset in this reading, which is normal. Operation of the module is straight forward. Just press V and turn the knob to set Voltage, Press A and turn the knob to set Current limit. When you are done, press Set and you see the confirmation screen. After that, by pressing ON/OFF button, output is enabled.
This is interesting because it is not just about turning the knob to change voltage – you have to press V button first. This is a nice feature because it is nice to know that your PSU output won’t change by accident. You can also adjust the voltage both on-line and off-line this way. The second feature is the ability to adjust setting before you enable the output. The knob is a standard rotary encoder that features a push switch, which is used to change the digit you adjust. After some minutes of use you will be able to familiarize with the interface.
DPS5020 power module
The image above shows the PSU module. Input is on the left and output on the right. At the front, you see an LQFP48 holding an STM32F100C8. The USB is a familiar CH340G IC operating on a UART. You can also see the small 4 pin connector next to the MCU. Using that connector you can remotely connect to the module using USB, Bluetooth or simply hacking the UART.

Software
The image above shows the top-side HMI that can be used to operate the module from a PC. You can hack the UART and connect a Graph display on the PSU + adding Ethernet/Wifi capabilities etc. For $45 with shipping included, it’s not a bad deal. The module has many advantages, with advanced functions, good visual interface, high precision, being used independently, being insert into your own box and been widely applied.
DPS5020 features
Testing
Testing DPS5020 module with a small 12V fan and multimeter.
We tested the module by connecting 12Vdc input and a small DC fan on the output. We set the voltage to 10Vdc and current limit to 1A. As you can see output voltage is off by only a few mV for this low power load.

Notes
You must make sure that the input voltage is 1.1 times higher than the output voltage. Under large current circumstances, pay attention to heat dissipation.
The connection between the display module and the power module should be according to the corresponding instructions. Otherwise, it will not work.
Input voltage range is DC 6-60V and 60v is the limit voltage; please leave a room to use, or else it will be burnt. The input must be DC Votlage input, not AC 220V, or else it will be burnt too.
Ruideng, also designs a range of power supplies and one of its smaller ones is particularly interesting. If the 5020 unit sounds a little over the top, there is also a little stand-alone version that fits all components in the front panel unit and this one comes from Banggood as well. This unit has a maximum of 20V @ 3 Amps. It is called DPS3003. It is very handy and needs just 20v DC input. No serial or Bluetooth is available, but it is also cheaper as it does not have a separate control board (it is all in the front panel) and would fit in a much smaller box.
You can buy the DPS5020 module from the attached (Banggood) link for 54.99 USD.
