Description
Demonstration circuit DC1477B features the
LTM
®
4609EV,
the high voltage, high efficiency, high density switch mode
buck-boost power module. The LTM4609EV regulates
an output voltage above, below, or equal to the input
voltage. DC1477B accepts an input voltage from 10V
to 36V with a preset output voltage of 30V at up to 3A.
Derating may be necessary for certain V
IN
, V
OUT
, and
thermal conditions. An optional input π filter is added on
the DC1477B to minimize the input ripple. The switching
frequency may be synchronized to an external clock from
200kHz to 400kHz to reduce undesirable frequency har-
monics and/or parallel multiple modules for even higher
output current. The LTM4609 data sheet must be read in
conjunction with this demo manual prior to working on
or modifying demo circuit DC1477B.
