RAA223012 700V AC/DC Buck Regulator with Ultra-Low Standby Power Preliminary Datasheet
●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 around 50kHz. PFM eliminates any potential audible noises while offering superior light-load efficiency and ultra-low power consumption (<10mW at no load). The efficiency is achieved up to 75%. The built-in frequency dithering further reduces EMI noise spectrum.
■The RAA223012 also features input brown-out protection that prevents input circuitry from the overcurrent at low input voltage,and hiccup protections for output fault conditions such as short-circuit, overload, over-voltage, and open feedback.
■The RAA223012 is available in a small SOT23-5,SO7 and SO8 packages.
●Features
■Ultra low standby power (<10mW)
■No audible noises
■Low quiescent current (<100μA)
■Output voltage as low as 3.3v
■Low EMI with frequency dithering
■TSOT23-5, SO8 and SO7 package
■Programmable PFM allows optimization of C OUT for various standby power requirements
■Protection features: Short-Circuit Protection (SCP), Overload Protection (OLP), Over-voltage Protection (OVP), open feedback protection, and Over-Temperature Protection (OTP)
