3.1VIN to 31VIN Isolated
µModule DC/DC Converter
with LDO Post Regulator
DESCRIPTION
The LTM®8058 is a 2kV AC isolated flyback µModule®
(micromodule) DC/DC converter with LDO post regulator.
Included in the package are the switching controller, power
switches, transformer, LDO, and all support components.
Operating over an input voltage range of 3.1V to 31V, the
LTM8058 supports an output voltage range of 2.5V to 13V,
set by a single resistor. There is also a linear post regulator
whose output voltage is adjustable from 1.2V to 12V as
set by a single resistor. Only output and input capacitors
are needed to finish the design. Other components may
be used to control the soft-start control and biasing.
The LTM8058 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 LTM8058 is
available with SnPb or RoHS compliant terminal finish.
