Power & Power Management

The Non-Isolated AC/DC Buck Converter family from Renesas is a series of universal input AC/DC switching buck regulators that feature a 700V integrated MOSFET capable of delivering up to 8W output power, with the output voltage as low as 3.3V, with variable package options. It features a unique constant-off-time control method that helps to achieve ultra-low standby power, negligible EMI, and no audible noise. This product family also supports secondary-side-feedback isolated flyback topology.
