RAA223011

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

The RAA223011 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 5W output power (Table 1). It

supports output voltage as low as 3.3V. For higher

power, use the RAA223021 device, and for low-cost

small power solutions (<2W) use the RAA223012

device (Table 2).

Features

▪ Ultra-low standby power (<10mW)

▪ No audible noise

▪ Low quiescent current (<100µA)

▪ Output voltage as low as 3.3V

▪ Low EMI with frequency dithering

▪ 5 Ld TSOT23, 7 Ld SOIC, and 8 Ld SOIC package

The RAA223011 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 30kHz. PFM eliminates

any potential audible noises while offering superior

light-load efficiency and ultra-low power consumption

(<10mW at no load). Efficiency is achieved up to

80%. The built-in frequency dithering further reduces

the EMI noise spectrum.

options

▪ Programmable PFM allows optimization of C

OUT

for various standby power requirements

▪ Protection features: Short-Circuit Protection (SCP),

Overload Protection (OLP), open feedback

protection, and Over-Temperature Protection

(OTP).

Applications

▪ Home appliances

The RAA223011 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, and open feedback.

▪ Home automation, IoT, and sensors

▪ Metering and Industry control

▪ Bias power
