MUNICH--([ BUSINESS WIRE ])--Power Integrations (Nasdaq: [ POWI ]), the leader in high-voltage integrated circuits for energy-efficient power conversion, today launched [ HiperPFS ], a family of power factor correction (PFC) controllers with integrated high-voltage power MOSFETs. [ HiperPFS ]devices leverage an innovative control scheme that optimizes efficiency at light load levels. Additionally, compared with designs that use discrete MOSFETs and controllers, [ HiperPFS ] devices dramatically reduce component count and board footprint while simplifying system design and enhancing reliability. [ HiperPFS ]devices come in an extremely compact, low-profile eSIPa" package and are suitable for PFC applications from 75 W to 1 kW.

Regulatory moves in Europe, the United States, and elsewhere mandate high power factor for many electronic products with power requirements over 75 W and for lighting products over 5 W. These rules are combined with numerous application-specific standards that require high power supply efficiency across the entire load range, from full load to as low as 10% load. High efficiency at light load is a challenge for traditional PFC approaches in which fixed MOSFET switching frequencies cause fixed switching losses on each cycle, even at light loads.

[ HiperPFS ]simplifies compliance with new and emerging energy-efficiency standards over a broad market space in applications such as PCs, LCD TVs, notebooks, appliances, pumps, motors, fans, printers, and LED lighting. Power Integrationsa™ innovative variable-frequency continuous conduction mode of operation (VF-CCM) minimizes switching losses by maintaining a low average switching frequency, while also varying the switching frequency in order to suppress EMI, the traditional challenge with continuous-conduction-mode solutions. Systems using [ HiperPFS ] typically save a core size on both the boost choke and common-mode EMI noise suppression choke, reducing overall system size and cost.

Comments product marketing manager David New: aOur innovative variable-frequency, continuous conduction mode controller enables the [ HiperPFS ] to realize all of the benefits of continuous-conduction mode operation while leveraging low-cost, small, simple EMI filters. Devices in the [ HiperPFS ]family are clearly leading the industry in light-load efficiency performance. [ HiperPFS ]provides a highly integrated PFC solution that significantly reduces the number of components on a BOM. Some benchmarked designs have reduced the parts count by 50.a

In common with Power Integrationsa™ other power conversion product families, [ HiperPFS ]includes comprehensive protection features such as integrated soft-start, fault and over-load protection, and hysteretic thermal shutdown.

[ HiperPFS ]devices are available now in PIa™s popular eSIPa" low-profile package priced from $1.53 each for 10,000-piece quantities. The product datasheet, design ideas, and introductory video are available now on the Power Integrations website at [ http://www.powerint.com/hiperpfs ].
