DESCRIPTION

The MPQ8636 is a fully-integrated, high-

frequency, synchronous, rectified, step-down,

switch-mode converter. It offers a very compact

solution to achieve 4A/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.



Programmable Switching Frequency from

200kHz to 1MHz

Non-Latch OCP, OVP, and Thermal

Shutdown



Output Adjustable from 0.611V to 13V

APPLICATIONS

The MPQ8636 uses Constant-On-Time (COT)

control to provide a fast transient response and

ease loop stabilization.



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.

All MPS parts are lead-free, halogen free, and adhere to the RoHS

directive. For MPS green status, please visit MPS website under Quality

Assurance.

Trademarks of Monolithic Power Systems, Inc.

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.

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.
