Overview

The RAA223012 demonstration boards (RTKA223012DR0010BU and RTKA223012DR0020BU) are high voltage buck converters that demonstrate low-cost high-performance non-isolated AC/DC conversion from a universal input of 85VAC to 265VAC, to a 5V output with output current up to 150mA. The board has built-in overcurrent, short-circuit, input brownout, and over-temperature protection, and is designed on a compact PCB with low-cost half-wave input rectification. RTKA223012DR0020BU comes with an RAA223012 in SOT23-5 package.
