Beschreibung
The RAA223021 evaluation board (RTKA223021DE0000BU) is a high voltage buck converter that demonstrates a low-cost high performance non-isolated AC/DC conversion from an universal input of 85VAC to 265VAC, to a 12V output with the output current up to 667mA.The board has built-in overcurrent, short-circuit, input brownout, and over-temperature protection, and is designed on a single side PCB with a full-wave input rectification. It is pre-compliant with conducted EMI requirements by EN55022/CISPR 22. RTKA223021DE0000BU uses the RAA223021 SOIC-7 packaged IC.
