Renesas Electronics Corporation Evaluation Board, Buck Regulator; Silicon Manufacturer Renesas RTKA223021DE0000BU

The RAA223021 Evaluation Board is a universal input AC/DC buck regulator designed by Renesas, capable of delivering up to 8W output power with an integrated 700V MOSFET. It supports output voltages as low as 3.3V and features constant off-time control for heavy loads and Pulse Frequency Modulation (PFM) for light loads, ensuring low power consumption and efficiency up to 80%. The board operates with ultra-low standby power consumption of less than 20mW and minimizes audible noise due to its PFM operation. Protection features include short-circuit, overload, overvoltage, and open feedback protections, along with input brownout protection. The device is housed in a compact 7-lead SOIC package, making it suitable for applications in home appliances, IoT devices, and industrial control systems. The evaluation board is RoHS compliant, facilitating its use in environmentally sensitive applications.
