PI Introduces Highly Integrated PFC IC for Compact Consumer Products and PCs

May 31st, 2013

Power Integrations today introduced HiperPFS™-2, a new family of high-efficiency, active-PFC ICs for offline applications from 100 W to 380 W. HiperPFS-2 ICs combine a boost PFC controller, driver, PFC power MOSFET, PFC diode and protection circuits in one package, enabling exceptionally compact designs ideal for small-form-factor power supplies as used in mini-tower PCs, all-in-one PCs, game console adapters and TVs.

The HiperPFS-2 controller uses a variable-frequency CCM algorithm providing up to 97% efficiency across the load spectrum from 20% to 100% and power factor greater than 0.9 at 20% load with 265 VAC input for designs over 200 W. Including line-connected sense elements, the new device contributes just 60 mW to a typical high-power adapter's 300 mW no-load budget. Conducted and radiated EMI are minimized due to the integrated soft-recovery diode and short parasitic inductance loop which results from the highly integrated, compact design.
