描述
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 the 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 a low-cost half-wave input rectification. It is pre-compliant with conducted and radiated EMI requirements by EN 55022/CISPR 22 and the 1.5kV surge test by IEC 61000-4-5 standard. RTKA223012DR0010BU comes with an RAA223012 in an SO8 package.
RTKA223012DR0020BU comes with an RAA223012 in an SOT23-5 package.
