Power Integrations Introduces Highly Integrated PFC IC for Compact Consumer Products and PCs
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 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 Comments Edward Ong, product marketing manager for Power Integrations: “The HiperPFS-2 device is the most highly integrated PFC solution available. This enables designers to cost-effectively meet the 80 PLUS Gold and Platinum efficiency standards in space-constrained PCs. The device’s excellent no-load performance simplifies design and reduces cost in high-power adapter applications targeting aggressive standby or no-load specifications.”
Key applications for HiperPFS-2 ICs include TVs, PCs, game console adapters, telecoms and industrial products such as blowers, motor drives and chargers. A new reference design based on the HiperPFS-2 IC, RDR-294, describes a 350 W output power boost CCM PFC board with wide range AC input. RDR-294 is able to attain > 97% efficiency for 230 VAC across a wide load range and > 0.9 PF at 20% load.
