RT8132A

High Efficiency Single Synchronous Buck PWM Controller

General Description

Features

^Richtek Mach Response^TMTechnology

^1% High Accuracy 0.8V Reference

^VCC Input Range : 4.5V to 13.2V

^VOUT Operating Range : 0.3V to 3.3V

^Power Stage Input Range : 1.5V to 24V

^Fixed Operating Frequency : 300kHz

^VIN Detection

The RT8132A PWM controller provides high efficiency,

excellent transient response, and highDC output accuracy

needed for CPU core, I/O, and chipset RAM supplies in

notebook computers.

Richtek Mach Response^TMtechnology is specifically

designed for providing 100ns “instant-on” response to

load transients while maintaining a relatively constant

switching frequency.

^LG_OCSET for Current Limit

^PGOOD Indicator

The RT8132A achieves high efficiency at a reduced cost

by eliminating the current sense resistor found in

traditional current mode PWMs. Efficiency is further

enhanced by its ability to drive very large synchronous

rectifier MOSFETs. The Buck conversion allows this device

to directly step down high voltage batteries at the highest

possible efficiency. The RT8132A provides an 1% high

accuracy 0.8V reference voltage with minimum 1mA

source/sink current for high accuracy output application.

^Embedded Bootstrap Switch

^High Side Gate Driver Pull Low Resistor (10kΩ)

^Current Limit with Low Side Current Sense Scheme

 Enable Function with Internal Pull High Current

 OVP/UVP/OTP/Pre-OVP/Current Limit

 Shutdown Current <100μA

Applications

 GenericDC-DC Power Regulator

 Mother Boards andDesktop Servers
