Description
The LTM®8046 is an isolated flyback DC/DC µModule®
(micromodule) converter. The LTM8046 has an isolation
rating of 2kVAC. 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 31V, the LTM8046 supports an output voltage range
of 1.8V to 12V, set by one resistor. Only output, input,
and bias capacitors are needed to finish the design. An
optional capacitor can be used to set the soft-start period.
The LTM8046 is packaged in a 9mm × 15mm × 4.92mm
over-molded ball grid array (BGA) package suitable for
automated assembly by standard surface mount equip-
ment. The LTM8046 is available with SnPb (BGA) or RoHS
compliant terminal finish.
