PFC IC enables compact designs for consumer products and PCs
HiperPFS-2 ICs combine a boost PFC controller, driver, PFC MOSFET, PFC diode and protection circuits in one package, enabling 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 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 a short parasitic inductance loop which results from the highly integrated, compact design.
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.
