Zero Voltage Switching Chipset Shrinks High-Power-Density Power Supply Units to 100W and Beyond

Posted on 5 July, 2021 by mixos

The innovative digital Zero Voltage Switching (ZVS) chipset from Dialog Semiconductor enables designers to reduce component size and BOM cost for delivering small form-factor, lightweight power supplies, including travel adapters for smartphones, tablets, laptops, power tools, and other portable devices. Targeting high power density PSUs with Zero Voltage switching technology, these new devices enable 100 Watt and beyond High Power Density (HPD) Power Supply Units (PSUs) that are 30-50% smaller than conventional high power PSUs.

The easy-to-use ZVS RapidCharge solution comes integrated with the iW9801 primary-side controller and the iW709 secondary-side USB PD protocol IC. Additionally, there is an integrated synchronous rectifier controller in the secondary-side iW709 further reduces the overall component count. This secondary-side digital compensation loop ensures stability and eliminates the need for extra compensation components.

The ZVS chipset solution enables customers to simply design higher power density chargers that are lightweight, ultra-small, and quite cost-effective. It offers robust protection for over-voltage (OVP), over-current (OCP), user-configurable over-temperature, shoot-through, brown-in/brown-out VSENSE/ISENSE short, output short, and extra primary-side OCP and OVP. Besides, low standby power of less than 20mW makes it an eco-friendly solution.

The chipset supports most fast charge protocols, including USB PD 3.0 with Programmable Power Supply (PPS) and other third-party proprietary protocols. With the option to employ switching frequencies up to 200 kHz, designers can use a much smaller and lighter transformer and smaller passive components thereby reducing the charger size and weight.

Lithium Battery Battery Management System with 3A Dual Output

Posted on 5 July, 2021 by Emmanuel Odunlade

California-based Embedded electronics solutions manufacturer; EZBriz, recently announced the launch of their Battery management board; the Lithium Battery BMS.

Battery management systems, in their advanced states, are electronic systems/devices that manages rechargeable batteries (cells or packs) to ensure optimum power delivery, safety, and improved battery life, by preventing the battery from operating outside stipulated operating conditions by monitoring its state, charging, and discharging, controlling its environment, balancing it, and calculating and reporting secondary data.

While the EZBriz Lithium Battery BMS is not on this level, the BMS provides the basic features of optimizing power supply and battery life, by ensuring battery charging and discharging are in accordance with the requirements of the 3.7v single-cell lithium batteries for which it was designed.

Compatible with 3.7v single-cell versions of both Lithium-polymer (Lipo) and Lithium-ion (18650, 21700, etc.,) batteries, the BMS features over-voltage, under-voltage, over-current, and short-circuit protection, which helps keep the battery in good condition. To conserve battery power and prevent leaks, the board also automatically turns off if no load is detected after a 30-second wait time.

Designed to serve the maker community, the BMS comes with both 3.3v and 5v outputs which can both be used at the same time without drops in output performance and ensuring a wide range of support for all sorts of development boards, since they are usually based on either of these voltages. Speaking about support for a wide range of development boards, the BMS features a combined 3A output current, which makes it good enough to power Single Board Computers like the Raspberry Pi and Nvidia Jetson range of boards.

The compact board is built around Texas Instrument’s TPS54331 buck converter and Injoinic IP5310 power management system-on-chip (SoC), though without taking advantage of the chip’s support for USB Type-C connectivity, as the team opted for a power jack to which a 5v output adapter can be connected for charging. Asides from the power jack input, the board also comes with a terminal block through which a 5vDC supply (Strictly 5V no tolerance) can be connected to the board to charge the battery.

One of the great features of the BMS board for me is the uninterruptible battery side power, which ensures that the connection or disconnection of the charger (via the Jack or Terminals) does not interfere with supply to the devices connected at the BMS output terminal.

The BMS board along with a compatible DC power supply is available on EZBriz’ Tindie store for $14.98, with shipping fees ranging from $8-9 depending on your desired courier.

More information on the Lithium battery board and its features are available on the project’s tindie page.

Newsmay’s Latest Mini PC is based on Intel Jasper Lake

Posted on 5 July, 2021 by Emmanuel Odunlade

With the interest in Mini-PC growing thanks to the growth being experienced across application feeds like Edge computing and Digital Displays, Intel at the beginning of the year announced the launch of the Jasper Lake processors to provide a more powerful processor for Mini PCs, and China-based mini-PC manufacturer, Newsmay technologies, has tapped up the processors in the new family to power their latest Mini PC; The AC8 Series.

The Jasper lake processors are a more powerful upgrade to the Gemini Lake processors which had dominated the Mini-PC market, and while there have been leaks and hearsays indicating they several manufacturers have a Jasper lake processor-powered Mini-PC in the work, the first one to the market is the AC8 series.

Fitted into a portable 127 x 127 x 48mm chassis, the Mini-PC AC8 comes in 3 flavors which represent 3 different processors options from which users can choose from including; the Intel Jasper Lake Celeron Processors Dual-Core N4505, the Quad Core N5105 (2.0GHz-2.9GHz), or the Intel Pentium Silver Processor N6005 (2.0GHz-3.3GHz), each with different thermal design power options ranging from 6 – 15W TDP.

Irrespective of the processor and thermal design power choice, the Mini-PC AC8 comes with 3 Display Ports with support for VGA DP and HDMI(at up to 4kp60) making it the perfect solution for multi-display applications, 2 SODIMM DDR4 slots which allow RAM expansions up to 32GB, multiple storage options including an M.2 SSD and an SD Card slot, multiple USB ports, multiple communication options including Ethernet, WiFi( 2.4G/5.2G), and Bluetooth 4.2 to mention a few features, all of which comes together to make the Mini-PC AC8 one of the “really complete” mini-PC on the market.

Asides from leveraging the Jasper Lake processors, one of the really cool features of the AC8 for me is the super quiet and cool fanless design. While the fanless design is definitely not new, the AC8 employs a honeycomb design for the top and bottom chassis which gives users the license to push the PC to its limits without worrying about heat.

Some highlight features of the Mini-PC AC8 include:

CPU: Intel Jasper Lake Celeron Processors Dual Core N4505; Quad Core N5105 (2.0GHz-2.9GHz); Intel Pentium Silver Processor N6005 (2.0GHz-3.3GHz).
