Renesas Electronics RAA223012 Demonstration Boards provide reference designs for low-cost, high-performance AC-DC conversion based on the RAA223012 700V Non-Isolated AC-DC Buck Regulator. The RAA223012 features ultra-low standby power and an integrated 700V MOSFET capable of delivering up to 2.5W output power. It supports output voltage as low as 3.3V. The RAA223012 combines constant off-time control for heavy load and Pulse Frequency Modulation (PFM) for light-load operation.
The Renesas Electronics RAA223012 Demonstration Boards features an AC-DC conversion circuit from a universal input of 85V to 265VAC to a 5V output with an output current up to 150mA. The Demonstration Boards have built-in overcurrent, short-circuit, input brownout, and over-temperature protection, and are designed on a compact PCB with a low-cost half-wave input rectification. These Boards are pre-compliant with conducted and radiated EMI requirements by EN55022/CISPR 22 and the 1.5kV surge test by IEC61000-4-5 standard.
The RTKA223012DR0010BU Demonstration Board includes the RAA223012 in a SOIC-8 package. The RTKA223012DR0020BU includes the RAA223012 in a TSOT-23-5 package. Both RAA223012 Demonstration Boards include built-in overcurrent, short-circuit, input brownout, and over-temperature protections.
