MPQ8636GV/MPQ8636HGV

High Efficiency, 20A, 18V

Synchronous, Step-Down Converter

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MPQ8636GV-20/MPQ8636HGV-20 is a

fully-integrated, high-frequency, synchronous,

rectified, step-down, switch-mode converter. It

offers a very compact solution to achieve 20A

output current over a wide input supply range,

with excellent load and line regulation. The

MPQ8636GV-20/MPQ8636HGV-20 operates at

high efficiency over a wide output-current–load

range.

•

Wide 4.5V-to-18V Operating Input Range

20A 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 Time

Pre-Bias Start-Up

•

The MPQ8636GV-20/MPQ8636HGV-20 uses

Constant-On-Time (COT) control to provide a

fast transient response and ease loop

stabilization.

Programmable Switching Frequency from

200kHz to 1MHz

•

Non-Latch OCP, OVP, and Thermal

Shutdown

Output Adjustable from 0.611V to 13V

An external resistor programs the operating

frequency from 200kHz to 1MHz, and the

frequency keeps nearly constant as input

supply

compensation.

APPLICATIONS

•

Telecom and Networking Systems

Base Stations

Servers

Personal Video Recorders

Flat-Panel Televisions and Monitors

Distributed Power Systems

The default under-voltage lockout threshold is

internally set at 4.1V, but a resistor network on

the enable pin can increase this threshold. The

soft-start pin controls the output-voltage startup

ramp. An open-drain power-good signal

indicates that the output is within nominal

voltage range.

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.

Monolithic Power Systems, Inc.

It has fully-integrated protection features that

include over-current protection, over-voltage

protection and thermal shutdown.

The MPQ8636GV-20/MPQ8636HGV-20 requires

a minimal number of readily-available, standard,

external components and is available in a

5mm×4mm 25-Pin QFN package.
