The LTM8048 is an isolated flyback μModule (power module) DC/DC converter with LDO post regulator. The LTM8048 has an isolation rating of 725VDC. 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 LTM8048 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, input, and bypass capacitors are needed to finish the design. Other components may be used to control the soft-start control and biasing.

The LTM8048 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 LTM8048 is available with SnPb (BGA) or RoHS compliant terminal finish.

Product Detail

Demo circuit 1560A is an isolated flyback μModule® DC/DC converter with LDO post regulator featuring LTM8048. The demo circuit is designed for a 6V flyback output and a 5V post regulator output from a 4.5V to 30V input. The typical current capability of the 6V flyback output varies with input voltage from about 110mA at VIN = 4.5V to about 370mA at VIN = 30V. The circuit provides 725VDC isolation.
