Evaluation Board , RAA223012, Power Management, Buck Regulator

RTKA223012 high voltage buck converter demonstration 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 5V output with the output current up to 150mA. The board has built-in overcurrent, short-circuit, input brownout, and over-temperature protection. It is designed on a compact PCB with a low-cost half-wave input rectification. It is pre-compliant with conducted and radiated EMI requirements by EN55022/CISPR 22 and the 1.5KV surge test by IEC61000-4-5 standard. It comes with a RAA223012 in SOT-23-5 package. Typical applications home appliances, home automation, IoT, sensors, metering, industry control and bias power.
