60V, 4A DC/DC µModule  
Regulator  
FEATURES  
DESCRIPTION  
The LTM®8027 is a complete 4A, DC/DC step-down power  
supply. Included in the package are the switching control-  
ler, power switches, inductor and all support components.  
Operatingoveraninputvoltagerangeof4.5Vto60V(7.5V  
minimum voltage to start), the LTM8027 supports output  
voltages up to 24V, and a switching frequency range of  
100kHz to 500kHz, each set by a single resistor. Only the  
bulk input and output filter capacitors are needed to finish  
the design.
