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.  
“MPS” and “The Future of Analog IC Technology” are Registered  
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.
