The LTM8068 is a 2kV AC isolated flyback μModule® (power module) 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 2.8V to 40V, the LTM8068 supports an output voltage range of 2.5V to 18V, set by a single resistor. There is also a linear post regulator whose output voltage is adjustable from 1.2V to 18V as set by a single resistor. Only output and input capacitors are needed to finish the design.

The LTM8068 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 LTM8068 is available with SnPb or RoHS compliant terminal finish.

Product Detail

The Demo Circuit 2358A is a 2kV AC isolated flyback μModule® DC/DC converter with LDO post regulator featuring the LTM8068. The demo circuit is designed for a 5.6V flyback output and a 5V post regulator output from a 4.5V to 40V input. The current capability of the 5.6V flyback output (VOUT1) varies with input voltage from about 200mA at 4.5VIN to about 460mA at 40VIN. The current capability of the 5V LDO output (VOUT2) is limited by either the VOUT1 loading or the 300mA current limit on the LDO post regulator itself. Figure 1 in the demo manual shows the maximum output current on VOUT1 when VOUT2 is not loaded, and VOUT2 when VOUT1 is unloaded.
