概述
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 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. It is pre-compliant with conducted and radiated EMI requirements per EN 55022/CISPR 22 and with the 1.5kV surge test per the IEC 61000-4-5 standard. The RTKA223012DR0010BU comes with an RAA223012 in an SO-8 package.
RTKA223012DR0020BU comes with an RAA223012 in an SOT23-5 package.
