FEATURES  
DESCRIPTION  
The LTM®8023 is a complete 2A, DC/DC step-down power  
supply.Includedinthepackagearetheswitchingcontroller,  
power switches, inductor, and all support components.  
Operating over an input voltage range of 3.6V to 36V, the  
LTM8023supportsanoutputvoltagerangeof0.8Vto10V,  
and a switching frequency range of 200kHz to 2.4MHz,  
eachsetbyasingleresistor. Onlythebulkinputandoutput  
filter capacitors are needed to finish the design.

Tiny, Low Profile, Surface Mount LGA (9mm ×  
11.25mm × 2.82mm) and BGA (9mm × 11.25mm ×  
3.42mm) Packages  
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.
