DEMO MANUAL DC1198B-B

 DESCRIPTION

LTM4607EV: High Density

Buck-Boost Power Module

Demonstration circuit DC1198B-B features the 
LTM

®

4607EV, a high effi ciency, high density switch mode 

buck-boost power module. The LTM4607EV can regulate 
its output voltage from input voltage both above and below 
the output. The board accepts an input voltage from 6V 
to 36V and is set for an output voltage of 12V. The rated 
load current is 5A in boost mode and 12A in step-down 
operation. Derating is necessary for certain V

and thermal conditions. The switching frequency can be 
synchronized to external clock operating from 200kHz to

 PERFORMANCE SUMMARY

400kHz. This clock input can be used to reduce undesir-
able frequency harmonics and reduce input and output 
ripple when  paralleling LTM4607 modules for even higher 
output current. The LTM4607 data sheet must be read 
in conjunction with this demo manual for working on or 
modifying the demo circuit DC1198B-B.
