LTM8031  
Ultralow Noise EMC 36V, 1A  
DC/DC µModule Regulator  
FEATURES  
DESCRIPTION  
The LTM®8031 is an electromagnetic compatible (EMC)  
36V, 1A DC/DC μModule® buck converter designed to  
meet the radiated emissions requirements of EN55022.  
Conducted emission requirements can be met by adding  
standardltercomponents.Includedinthepackagearethe  
switching controller, power switches, inductor, lters and  
all support components. Operating over an input voltage  
range of 3.6V to 36V, the LTM8031 supports an output  
voltage range of 0.8V to 10V, and a switching frequency  
range of 200kHz to 2.4MHz, each set by a single resistor.  
Only the bulk input and output filter capacitors are needed  
to finish the design. The low profile package (2.82mm)  
enables utilization of unused space on the bottom of PC  
boards for high density point of load regulation.
