Description
2A, 36V DC/DC  
Step-Down µModule  
Regulator
supply. Included in the package are the switching controller, 
power switches, inductor, and all support components. 
Operating over an input voltage range of 3.6V to 36V, the 
LTM8023 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 enables utilization of unused 
space on the bottom of PC boards for high density point 
of load regulation.
The LTM8023 is packaged in a thermally enhanced, com-
pact and low profile over-molded land grid array (LGA) 
and ball grid array (BGA) packages suitable for automated 
assembly by standard surface mount equipment. The 
LTM8023 is available with SnPb (BGA) or RoHS compli-
ant terminal finish.
