.

Key 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 (.

RAA223021 700V AC/DC Buck Regulator with Ultra-Low Standby Power Datasheet 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.
