Typical Application

Description

The LTM®8057 is a 2kV AC isolated flyback μModule® (power module) DC/DC converter. 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 LTM8057 supports an output voltage range of 2.5V to 12V, 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 LTM8057 is packaged in a thermally enhanced, compact (9mm × 11.25mm × 4.92mm) overmolded ball grid array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8057 is available with SnPb or RoHS compliant terminal finish.
