RAA23021x

5.5V Input, 3A, Step-Down DC/DC Converter + LDO

R18DS0013EJ0102

Rev.1.02

Jul 23, 2014

Description

The RAA23021x is a high efficiency monolithic step-down DC/DC synchronous converter plus a LDO (low dropout)

regulator which has an ultra-low power mode.

Features

•

DC/DC converter (ch1)

⎯ Synchronous rectification type step-down circuit

⎯ Integrated power MOSFETs

⎯ Preset output voltage (There are also products that have adjustable output voltage using external resistors.)

⎯ Internal phase compensator

⎯ Switching frequency: 1 MHz (fixed)

⎯ Internal timer-latch-type short-circuit protector (fixed delay time)

⎯ 100% duty cycle operation

•

LDO (ch2)

⎯ 500mA

⎯ Internal over current protector (foldback-current limiting)

⎯ Ultra low-power save mode (25uA typical)

Common Features

⎯ Internal rise up sequencer

⎯ Internal digital soft-start function (2 ms fixed soft-start time)

⎯ Internal discharge circuit

⎯ Power good function

⎯ Internal timer-latch-type thermal shutdown circuit (shutdown temperature: 150°C or higher)

⎯ Internal recovery-type under voltage lockout circuit

Application

⎯ Communication

⎯ Industrial

⎯ Building

⎯ Smart meter

And, usable around MCU, ASIC, FPGA, etc.
