DESCRIPTION
The LTM®8047 is an isolated flyback µModule DC/DC
converter. The LTM8047 has an isolation rating of 725VDC.
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. Operating over an input voltage range of 3.1V
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.
The LTM8047 is packaged in a thermally enhanced, com-
pact (11.25mm × 9mm × 4.92mm) over-molded ball grid
array (BGA) package suitable for automated assembly by
standard surface mount equipment. The LTM8047 is avail-
able with SnPb (BGA) or RoHS compliant terminal finish.
