RTKA223011DE0000BU

RAA223011 high voltage buck 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 300mA. The board has built-in overcurrent, short-circuit, input brownout and overtemperature protection. The board is designed on a single side PCB with a single diode half-wave input rectification. It is pre-compliant with conducted and radiated EMI requirements by EN55022/CISPR 22. It comes with a RAA223011 in a 5 Ld TSOT23 package. Typical applications home appliances, home automation, IoT, sensors, metering, industry control and bias power.
