PFC ICs enable 98% efficient designs up to 550 W
31 March 2017
Power Integrations announced its HiperPFSTM-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 uniformly high efficiency across a wide output load range, allowing OEMs to meet the demanding 80 PLUS Platinum and Titanium power supply standards.
HiperPFS-4 ICs achieve a high power factor of above 0.95 and low THD even 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 VAC input test, which ensures field reliability and robustness against voltage swells and surges.
The new HiperPFS-4 ICs suit enclosed designs up 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 60 mW at 230 VAC while regulating output at no-load and less than 20 mW in sleep mode.
