RAA211650

60V 5A Integrated Switching Regulator

The RAA211650 is an integrated 60V, 5A

Features

▪ 4.5V to 60V input supply range

synchronous buck regulator with adjustable switching

frequency from 200kHz up to 2.5MHz. It supports a

wide input voltage range from 4.5V to 60V and

adjustable output voltage (0.8V to maximum duty

▪ Integrated high-side (90mΩ) and low-side (37mΩ)

MOSFETs

cycle * V ). The integrated low r

MOSFETs,

DS(ON)

▪ 1% accurate voltage reference over temperature

gate drivers, and the controller make RAA211650 an

efficient voltage step-down solution.

▪ Fixed-frequency operation with optional spread

spectrum and external clock sync

The device switches at a default frequency of

500kHz if the RT pin is tied to AVCC, however, it can

be programmed to switch from 200kHz to 2.5MHz by

using an external resistor on the RT pin. The

MODE/SYNC pin can dither the oscillator frequency

if the spread-spectrum operation is required. The

internal oscillator can also be synchronized to an

external clock through the MODE/SYNC pin. The

integrated regulator also has options either to use

internal fixed compensation or user-selected external

compensation.

▪ Adjustable switching frequency from 200kHz to

2.5MHz

▪ Programmable soft-start timing

▪ Programmable startup and shutdown delays

▪ Bidirectional overcurrent protection on both

internal FETs

▪ Extensive voltage and temperature protection

▪ Compact 28 Ld 4x5mm QFN package

Applications

To limit inrush current during startup, RAA211650

has 2ms fixed internal soft-start time. It can also be

programed by an external capacitor.

▪ Industrial power supplies

▪ 12V/48V industrial and computing PoL

▪ ATM, vending, and gaming machines

▪ Robotics

The RAA211650 provides programmable startup

delay time for sequencing purposes. Also, the

RAA211650 provides comprehensive protections

including undervoltage lockout, overcurrent (positive

and negative), overvoltage, and over-temperature.

▪ Programmable Logic Controllers

▪ After-market automotive

The device is available in a 28 Ld 4mmx5mm QFN

package.
