PFS757
Description
The HiperTFS device family members incorporate both a high-power two-switch-forward converter and a mid-power flyback (standby) converter into a single, low-profile eSIP™ power package. The single chip solution provides the controllers for the two-switch-forward and flyback converters, high- and low-side drivers, all three of the high-voltage power MOSFETs, and eliminates the converter’s need for costly external pulse transformers.
