Микросхемы и комплектующие RTKA223021DE0010BU

RAA223021 high voltage flyback converter evaluation board is designed to demonstrate a low-cost high performance non-isolated AC/DC conversion from a universal input of 85VAC to 265VAC, to a 12V output with the output current up to 1A. The board has built-in overcurrent, short-circuit, input brownout and overtemperature protection. The board is designed on a double side Printed Circuit Board (PCB) with a full-wave input rectification. It is pre-compliant with the conducted EMI requirements by EN55022/CISPR 22. It uses the RAA223021 SOIC-7 packaged IC. Typical applications home appliances, home automation, IoT, sensors, metering, industry control and bias power.
