RTKA223011DE0000BU
Evaluation Board
The RAA223011 evaluation board (RTKA223011DE0000BU) is a high voltage buck converter that is designed to
demonstrate a low-cost high performance non-isolated AC/DC conversion from an universal input of 85V
to
AC
265V
, to a 12V output with the output current up to 300mA.
AC
The RTKA223011DE0000BU has built-in overcurrent, short-circuit, input brownout, and over-temperature
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.
RTKA223011DE0000BU comes with a RAA223011 in a 5 Ld TSOT23 package.
