High Power PFC Controller with Integrated High-Voltage MOSFET and Qspeed™ Diode

This product is in End-of-Life status and is no longer available.
Suggested Alternative: HiperPFS-3 HiperPFS-4

Product Details


The HiperPFS-2 family features ICs with a high level of integration including a CCM boost PFC controller, gate driver, ultra-low reverse recovery diode and high-voltage power MOSFET in a single, low-profile eSIP™ package. Other features include an integrated non-linear amplifier for enhanced load transient response, a user programmable power good (PG) signal and user selectable power limit functionality. HiperPFS-2 devices also provide cycle-by-cycle current limit for the power MOSFET, power limiting of the output for overload protection, and pin-to-pin short-circuit protection.

HiperPFS-2 devices are suitable for PFC applications from 75 W to 425 W and simplify compliance with new and emerging energy-efficiency standards over a broad market space in applications such as PCs, LCD TVs, notebooks, appliances, pumps, motors, fans, printers, and LED lighting.
