LTM8068

2.8V to 40V Isolated

µModule DC/DC Converter

with LDO Post Regulator

FEATURES

DESCRIPTION

The LTM^®8068 is a 2kVAC isolated flyback µModule^®

(power module) DC/DC converter with LDO post regula-

tor. Included in the package are the switching controller,

power switches, transformer, LDO, and all support com-

ponents. Operating over an input voltage range of 2.8V to

40V, the LTM8068 supports an output voltage range of

2.5V to 18V, set by a single resistor. There is also a linear

post regulator whose output voltage is adjustable from

1.2V to 18V as set by a single resistor. Only output and

input capacitors are needed to finish the design.
