Low-Cost, Dual-Output, Step-Down  
Controller with Fast Transient Response  
MAX864  
General Description  
Features  
The MAX8664 dual-output PWM controller is a low-cost,  
high-performance solution for systems requiring dual  
power supplies. It provides two individual outputs that  
operate 180° out-of-phase to minimize input current  
ripple, and therefore, capacitance requirements. Built-in  
drivers are capable of driving external MOSFETs to  
deliver up to 25A output current from each channel.  
The MAX8664 operates from a 4.5V to 28V input volt-  
age source and generates output voltages from 0.6V  
up to 90% of the input voltage on each channel. Total  
output regulation error is less than 0.8% over load,  
line, and temperature.

The MAX8664 operates with a constant switching fre-  
quency adjustable from 100kHz to 1MHz. Built-in boost  
diodes reduce external component count. Digital soft-  
start eliminates input inrush current during startup. The  
second output has an optional external REFIN2, facili-  
tating tracking supply applications. Each output is  
capable of sourcing and sinking current, making the  
device a great solution for DDR applications.

The MAX8664 employs Maxim’s proprietary peak volt-  
age-mode control architecture that provides superior  
transient response during either load or line transients.  
This architecture is easily stabilized using two resistors  
and one capacitor for any type of output capacitors. Fast  
transient response requires less output capacitance,  
consequently reducing total system cost. The MAX8664B  
latches off both controllers during a fault condition, while  
the MAX8664A allows one controller to continue to func-  
tion when there is a fault in the other controller.
