The RAA223021 is a universal input AC/DC switching buck regulator with ultra-low standby power that features a 700V integrated MOSFET capable of delivering up to 12W output power. It supports output voltage as low as 5V.
The RAA223021 combines constant off-time control for heavy load and Pulse Frequency Modulation (PFM) for light-load operation. Constant off-time controls switching frequency above the audible frequency around 43kHz. PFM eliminates any potential audible noises while offering superior light-load efficiency and ultra low power consumption (<20mW at no load). The efficiency is achieved up to 80%. The built-in frequency dithering further reduces EMI noise spectrum.
The RAA223021 also features input brownout protection that prevents input circuitry from the overcurrent at low input voltage, and hiccup protections for output fault conditions such as short-circuit, overload, overvoltage, and open feedback.
The RAA223021 is available in a small 7 Ld SOIC package.
