Regulator
Demonstration circuit DC1477A features the LTM
®
4609EV,
a 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.
DC1477A 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

and thermal conditions.
An input π filter option is included on the DC1477A to
minimize the input ripple. The switching frequency may
be synchronized to an external clock from 200kHz to
