The RAA223012 demonstration boards (RTKA223012DR0050BU and RTKA223012DR0060BU) are high voltage buck or buck/boost converters that demonstrate low-cost high-performance non-isolated AC/DC conversion from a universal input of 85VAC to 265VAC, to a 5V output or a -5V output, with output current up to 150mA. The board can be configured to a Buck or a Buck/Boost converter by using jumper (JP1) without changing the output polarity. RTKA223012DR0050BU comes with an RAA223012 in an SO8 package
