PFC ICs enable 98%-efficient designs to 550W
HiperPFS-4 devices incorporate a 600V 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 HiperPFS-4 ICs can be used on enclosed designs up to 300W, open frame power supplies of up to 400W and highline applications up to 550W. 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.
Power Integrations adds that its frequency-sliding control technology enablee 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 the IC family ideal for use in regions where input voltage fluctuations can be severe. HiperPFS-4 devices provide safe PFC operation with a good margin at 305 VAC input 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.”
In eeSIP packaging, which simplifies heatsink mounting, the parts cost $1.46 (10,000).
