  • Enables 98% Efficient PFC Designs Up to550 W

PI HiperPFS 4 March 17

Power Integrations today announced its HiperPFS-4 family of power factor correction (PFC) ICs. The new device family serves applications targeting excellent efficiency and power factor performance at both full load and light load conditions.

HiperPFS-4 devices incorporate a 600 V MOSFET suitable for 305 VAC input and a high efficiency, variable frequency, CCM PFC controller in a single, compact, electrically isolated,heatsinkable package. The IC family delivers high power factor, low THD and uniformlyhigh efficiency across a wide output load range, allowing OEMs to meetthe demanding 80 PLUS®Platinum and Titanium power supply standards.

HiperPFS-4 ICs achieve a high power factorof above 0.95 and low THDeven at 20% of rated load. The devices also meet the stringent surge requirements of major computer and entertainment equipment providers, such as the 1 second 410 VACinput test, which ensures field reliability and robustness against voltage swells and surges.

The new HiperPFS-4 ICs suit enclosed designsup to 300 W, open frame power supplies of up to 400 W and highline applications up to 550 W.Protection features include UVLO, UV, OV, OTP, brown-in/out, cycle-by-cycle current limit and power limit.HiperPFS-4 ICs consume less than 60mW at 230 VAC while regulating output at no-load andless than 20 mW in sleep mode.

Comments Edward Ong, product marketing manager at Power Integrations: “The HiperPFS-4 product family offers very high efficiency and power factor plus low THD across a wide load range. The benefits afforded by the unique frequency-sliding control technology enable HiperPFS-4 designs to deliver very high efficiency down to very light load – important when targeting EU CoC  requirements that include a 10% load efficiency measurement.

The 600 V integrated power MOSFET and sophisticated protection features make theIC family ideal for use in regions where input voltage fluctuations can be severe.HiperPFS-4 devices provide safe PFC operationwitha good marginat 305VACinput for data centers and commercial LED lighting. Other applications include refrigerators (which increasingly contain high PFC specification requirements),cordless tool chargers and eBike battery chargers.”

Available for high and low line applications, HiperPFS-4 ICs are available in thermally-efficient eeSIP packaging,which simplifies heatsink mounting. Devices cost $1.46 in 10,000-piece quantities. Please visit www.power.com/products/hiperpfs-4/.
