Open Source MCU Platforms 3056: Adafruit Feather WICED WiFi - STM32F205 with Cypress WICED WiFi Manufacturer: Adafruit Industries LLC

The WICED Feather is based on Broadcom's WICED (Wireless Internet Connectivity for Embedded Devices) platform, and is paired up with a powerful STM32F205 ARM Cortex M3 processor running at 120MHz, with support for TLS 1.2 to access sites and web services safely and securely.

AC/DC and DC/DC Conversion > DC/DC SMPS - Single Output EVB_RT2856GQW: 3.3V @ 6A, 4.5 ~ 18Vin Manufacturer: Richtek USA Inc.

The RT2856GQW is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 6A output current from a 4.5V to 18V input supply. The RT2856GQW current-mode architecture with externalcompensation allows the transient response to be optimized over a wide range of loads and output capacitors.

AC/DC and DC/DC Conversion > AC/DC SMPS - Single Output RDK-420: 5V @ 2A, 10W, 85 ~ 264V in Manufacturer: Power Integrations

This document is an engineering report describing a 2 A, 5.0 V USB charger utilizing a device from the InnoSwitch-CH family of ICs. This design is intended to show the high power density and efficiency that is possible due to the high level of integration while still providing exceptional performance.
