LTM8047 - 3.1VIN to 32VIN Isolated μModule (Power Module) DC/DC Converter

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, compact (11.25mm × 9mm × 4.92mm) over-molded ball grid array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8047 is available with SnPb (BGA) or RoHS compliant terminal finish.
