LTM8047

3.1V to 32V Isolated

µModule DC/DC Converter

FEATURES

DESCRIPTION

Complete Switch Mode Power Supply

The LTM^®8047 is an isolated flyback µModule DC/DC

converter.TheLTM8047hasanisolationratingof725VDC.

For a similar product with LDO post regulator, see the

LTM8048. Included in the package are the switching

controller, power switches, transformer, and all support

components.Operatingoveraninputvoltagerangeof3.1V

to 32V, the LTM8047 supports an output voltage range of

2.5V to 12V, set by a single resistor. Only output, input,

and bypass capacitors are needed to finish the design.

Other components may be used to control the soft-start

control and biasing.
