DESCRIPTION

µModule DC/DC Converter

with LDO Post Regulator

(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.

The LTM8068 is packaged in a thermally enhanced, com-

pact (9mm × 11.25mm × 4.92mm) overmolded ball grid

array (BGA) package suitable for automated assembly

by standard surface mount equipment. The LTM8068 is

available with SnPb or RoHS compliant terminal finish.
