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

The RAA223010 is a universal input AC/DC switching

buck regulator with ultra-low standby power that

features a 700V integrated MOSFET capable of

delivering 10W output power. It supports output

voltage as low as 3.3V.

Features

▪ Ultra-low standby power (<15mW)

▪ No audible noise

▪ Low quiescent current (<75µA)

▪ Output voltage as low as 3.3V

▪ Low EMI with frequency dithering

▪ 7 Ld SOIC package

The RAA223010 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 45kHz. PFM eliminates any

potential noises while offering superior light-load

efficiency and ultra-low power consumption (<15mW

at no load). The efficiency is achieved up to 80%. The

built-in frequency dithering further reduces the EMI

noise spectrum.

▪ Programmable PFM allows optimization of C

OUT

for various standby power requirements

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

Overload Protection (OLP), Overvoltage Protection

(OVP), open feedback protection, and

Over-Temperature Protection (OTP).

The RAA223010 features input brownout protection

that prevents input circuitry from overcurrent at low

input voltage. The device also features hiccup

protections for output fault conditions such as

short-circuit, overload, overvoltage, and open

feedback.

Applications

▪ Home appliances

▪ Home automation, IoT, and sensors

▪ Metering and Industry control

▪ Bias power

The RAA223010 is available in a small 7 Ld SOIC

package.
