LTM4650A-1  
Dual 25A or Single 50A  
DC/DC µModule Regulator  
with 1% DC Accuracy  
DESCRIPTION  
The LTM®4650A-1 is a dual 25A or single 50A output  
switchingmodestep-downDC/DCµModule® (micromod-  
ule) regulator with 1% total DC output error. Included in  
the package are the switching controllers, power FETs,  
inductors and all supporting components. Operating from  
an input voltage range of 4.5V to 16V, the LTM4650A-1  
supports two outputs with an output voltage range of 0.6V  
to 5.5V, each set by a single external resistor. Its high ef-  
ficiency design delivers up to 25A continuous current for  
each output. Only a few input and output capacitors are  
needed. Adjustable control loop compensation allows for  
fast transient response to minimize output capacitance  
when powering FPGAs, ASICs, and processors.
