Description

The HiperPFS?-5 family of advanced power factor correction ICs

leverages the low switching losses of the 750 V PowiGaN switch to

optimize efficiency. The high integration level and novel control

algorithm minimize system footprint by reducing overall component

count and inductor size. Packaged in the low profile, surface mount

InSOP-T28F, the device dissipates heat directly to the PCB substrate,

eliminating the need for bulky heat sinks. Robust HiperPFS-5 devices

operate from low-line to 305 VAC with over 80 de-rating.
