Multi-port 65W fast charger reference design

Silanna Semiconductor has launched a fully integrated reference design for 65W multiport faster chargers in a 1C1A format.

The RD-35 design is built around Silanna’s AC-DC controller and DC-DC converter technology and featuring a silicon superjunction FET for fast chargers with one USB Type-A and one Type-C interface (1C1A) delivering up to 3.25A.

The operating efficiency greater than 92% minimizes power consumption during charging, while no-load consumption of less than 300 mW reduces standby power. Efficiency is relatively flat across the universal (90 – 265Vac) input voltage range and low-to full-load conditions.

The RD-35 combines Silanna’s 16pin SZ1131 fully-integrated AC-DC active clamp flyback (ACF) controller and the company’s SZPL3102A high-voltage, high-efficiency integrated 65W buck converter. The AnyPort architecture provides the flexibility to complete a charger design for a given power level prior to specifying and configuring the specific number and type of output ports.

This allows a single base charger design to be deployed across various end products with different Type-C and Type-A output configurations. Time-to-market is further reduced as the RD-35 exceeds conducted and radiated EMI requirements, eliminating the need for pre-production validation and certification.

“Manufacturers are looking to create multi-port fast chargers that address stringent performance, power density and efficiency requirements within tight time-to-market deadlines,” says Ahsan Zaman, Silanna Semiconductor’s Director of Product Marketing.

“In line with our other production-ready reference designs, the combination of Silanna’s CO2 Smart Power family of advanced AC/DC and DC/DC technologies and the innovative AnyPort architecture enable engineers to reduce the time needed to develop and test 65W 1C1A multi-port designs and ensure the fastest possible route from prototyping to full production.”

Full availability of PCB Gerber and production files further reduces the time from prototyping to full production.

A camera for motion photography and machine vision

The Raspberry Pi Global Shutter Camera is a specialized 1.6-megapixel camera that is able to capture rapid motion without introducing artifacts typical of rolling shutter cameras. It is ideally suited to fast motion photography and to machine vision applications, where even small amounts of distortion can seriously degrade inference performance.

Specification

  • Form factor: 38 × 38 × 19.8mm (29.5mm adapter and dust cap)
  • Weight: 34g (41g with adapter and dust cap)
  • Sensor: Sony IMX296LQR-C
  • Resolution: 1.58 megapixels (color)
  • Sensor size: 6.3mm sensor diagonal
  • Pixel size: 3.45μm × 3.45μm
  • Output: RAW10
  • Back focus length of lens: Adjustable (12.5–22.4mm)
  • Lens standards: CS-Mount, C-Mount (C-CS adapter included)
  • IR cut filter: Integrated
  • Ribbon cable length: 150mm
  • Included accessories: C-CS mount adapter, screwdriver
  • Tripod mount: 1/4”-20

With a large pixel size of 3.45μm × 3.45μm providing high light sensitivity, the Global Shutter Camera can operate with short exposure times (as low as 30μs with adequate lighting), an advantage for high-speed photography.

It features a 1.6MP Sony IMX296 sensor, and it has the same C/CS-mount lens assembly as the Raspberry Pi High-Quality Camera, for compatibility with the same broad variety of lenses. In common with other global shutter sensors, the IMX296 has a lower resolution than similarly sized rolling shutter sensors; a low pixel count is appropriate for machine vision applications, where high-resolution images are challenging to process in real-time. The Global Shutter Camera’s lower resolution means that with appropriate lens magnification, an image suitable for processing by a machine vision model can be captured natively.

The Raspberry Pi Global Shutter Camera includes a C- to CS-mount adapter, a screwdriver, and a 150mm ribbon cable, as well as a removable plastic back cover for protection. It is compatible with any Raspberry Pi computer that has a CSI connector.

Texas Instruments OPT3005 Ambient Light Sensor (ALS)

Texas Instruments OPT3005 Ambient Light Sensor (ALS) is a single-chip lux meter measuring the intensity of light as visible by the human eye. The extreme IR rejection and precision spectral response of the OPT3005 enable it to accurately meter the intensity of light as seen by the human eye regardless of the light source and any stray light from 850nm or 940nm active illumination. The extreme IR rejection helps to maintain high accuracy when industrial design calls for mounting the sensor under the dark glass, especially with active 850nm or 940nm NIR illumination. These systems typically have a lot of NIR stray reflections from the cover glass, which can affect the light sensor measurement. The precision optical filtering of OPT3005 is verified for resilience to such stray NIR reflection and truly measures the ambient light as perceived by the human eye.

The Texas Instruments OPT3005 is designed for systems that create light-based experiences for humans. It is a preferred replacement for photoresistors, photodiodes, or other ambient light sensors with less human eye matching and IR rejection.

Inside the board, however, GPIO16, GPIO17, GPIO18, GPIO19, GPIO20, and GPIO21 are all linked to W6100. These pins let the W5100S communicate to the SPI to use the Ethernet function. In the case of using the Ethernet function, it cannot use these pins for anything else.

  • It offers support for hardwired internet protocols such as TCP, UDP, IPv6, IPv4, ICMPv6, ICMPv4, IGMP, MLDv1, ARP, and PPPoE. In addition to this, it is capable of simultaneously supporting eight separate sockets and has 32 kB of memory.
  • Serial Peripheral Interface: A Micro-USB B port for power and data (as well as for reprogramming the Flash) is provided. A 40-pin, 21×51 “DIP”-style printed circuit board with 0.1″ through-hole pins and edge castellations is one of the features of this product. In addition to that, it features a 3-pin ARM Serial Wire Debug (SWD) port and an inbuilt 10/100 Ethernet PHY. It is compatible with Automatic Negotiation. It built-in RJ45 (RB1-125BAG1A) and built-in LDO (LM8805SF5-33V)
  • The dimension is 75 x 21 mm.

A brief IPv4/IPv6 tutorial for this board is available on Hackster.io for the Arduino IDE. Moreover, a GitHub repository, including several examples, such as UDP, WebClient, Webserver, etc., is accessible.

On Mouser.com, the W6100-EVB-PICO is available for $17.58. Yet, even when these gadgets are out of stock, you can still order them on backorder.
