DESCRIPTION
Demonstration circuit DC1198A-B features the
LTM
4607EV, a high efficiency, 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

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 DC1198A-B.
