DESCRIPTION

The MPQ8636 is a fully-integrated, high-

frequency, synchronous, rectified, step-down,

switch-mode converter. It offers a very compact

solution to achieve 10A/20A output current over a

wide input supply range, with excellent load and

line regulation. The MPQ8636 operates at high

efficiency over a wide output-current–load range.



Non-Latch OCP, OVP, and Thermal

Shutdown

Output Adjustable from 0.611V to 13V

The MPQ8636 uses Constant-On-Time (COT)

control to provide a fast transient response and

ease loop stabilization.

APPLICATIONS



Telecom and Networking Systems

Base Stations

Servers

Personal Video Recorders

Flat-Panel Televisions and Monitors

Distributed Power Systems

An external resistor programs the operating

frequency from 200kHz to 1MHz, and the

frequency keeps nearly constant as input

supply

varies

with

the

feed-forward

compensation.

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 MPQ8636 requires a minimal number of

readily-available standard external components

and is available in a 16-Pin QFN 3mm×4mm or a

29-Pin QFN 5mm×4mm package.
