MPQ8632D-6, MPQ8632D-12

High Efficiency, 6A/12A, 18V

Synchronous Step-down Converter

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MPQ8632D-6/MPQ8632D-12 is a fully

integrated high frequency synchronous rectified

step-down switch mode converter. It offers a

very compact solution to achieve 6A/12A output

current over a wide input supply range with

excellent load and line regulation. The

MPQ8632D-6/MPQ8632D-12 operates at high

efficiency over a wide output current load range.

•

2.5V to 18V Operating Input Range with

External 5V Bias

4.5V to 18V Operating Input Range with

Internal Bias

•

6A/12A Output Current

Low R_DS(ON) Internal Power MOSFETs

Proprietary Switching Loss Reduction

Technique

•

Adaptive COT for Ultrafast Transient

Response

0.5% Reference Voltage Over 0°C to 70°C

Junction Temperature Range

Programmable Soft Start and Shut-down

Time

Pre-Bias Start up

Programmable Switching Frequency from

200kHz to 1MHz

The

MPQ8632D-6/MPQ8632D-12

uses

Constant-On-Time (COT) control mode to

provide fast transient response and ease loop

stabilization.

An external resistor programs the operating

frequency from 200kHz to 1MHz and the

frequency keeps nearly constant as input

supply

compensation.

with

the

feedforward

•

Non-latch OCP, OVP and Thermal

Shutdown

Output Adjustable from 0.611V to 13V

The default under voltage lockout threshold is

internally set at 4.1V, but a resistor network on

the enable pin can increase this threshold. An

open drain power good signal indicates that the

output is within nominal voltage range.

APPLICATIONS

•

Telecom and Networking Systems

Base Stations

Servers

Personal Video Recorders

Flat Panel Television and Monitors

Distributed Power Systems

The MPQ8632D-6/MPQ8632D-12 employs a

programmable soft start and shut-down scheme.

With the soft shut-down feature, it discharges

the output voltage smoothly when the enable

signal is deserted.

It has fully integrated protection features that

include over-current protection, over-voltage

protection and thermal shutdown.

All MPS parts are lead-free and adhere to the RoHS directive. For MPS green

status, please visit MPS website under Products, Quality Assurance page.

The MPQ8632D-6/MPQ8632D-12 requires a

minimal number of readily available standard

external components and is available in a

3mm×4mm package.
