RAA2230124GSP#HA0

RAA223012 is an universal input AC/DC switching buck regulator with ultra-low standby power that features a 700V integrated 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. Constant off-time controls switching frequency above the audible frequency of approximately 50KHz. PFM eliminates any potential audible noises while offering superior light-load efficiency and ultra-low power consumption (<lt/>10mW at no load). Efficiency is achieved up to 75%. The RAA223012 also features input brownout protection that prevents input circuitry from the overcurrent at low input voltage. Typical applications include home appliances, home automation, IoT, sensors, metering, industry control and bias power.

• Ultra-low standby power (<lt/>10mW)
• No audible noise
• Low quiescent current (<lt/>100µA)
• Low EMI with frequency dithering
• Programmable PFM allows optimization of COUT for various standby power requirements
• Overtemperature protection (OTP)
• Built-in frequency dithering further reduces the EMI noise spectrum
• Hicc-up protections for output fault conditions such as short-circuit, overload and open feedback
