MUNICH--([ BUSINESS WIRE ])--Power Integrations (Nasdaq: [ POWI ]), the leader in high-voltage integrated circuits for energy-efficient power conversion, today introduced [ HiperTFS ], a highly integrated power supply IC family for high-power applications. Uniquely, [ HiperTFS ]device family members incorporate both a two-switch-forward converter and a flyback standby power converter into a single, low-profile eSIPa" power package. As well as the two controllers, [ HiperTFS ] devices include high- and low-side drivers and all of the high-voltage power MOSFETs for the main and standby power converters. Therefore, [ HiperTFS ]is an ideal product for consumer, computer, and industrial power supply designs requiring main power from 120 W to 415 W and a standby converter capable of up to 20W. The new devices particularly target applications requiring high efficiency and compact form factor, such as desktop PCs, TVs, and video game consoles.

Two-switch-forward power converters are often selected for applications demanding cost-effective efficiency, fast transient response, and accurate tolerance to line voltage fluctuation. The two-switch-forward controller incorporated into [ HiperTFS ] devices improves on the classic topology by allowing operation considerably above 60% duty cycle. This improvement reduces RMS currents - and therefore conduction losses - and also minimizes the size and cost of the bulk capacitor. The advanced design also includes transformer flux reset control and charge-recovery switching of the high-side MOSFET, which reduces switching losses. This combination of innovations yields an extremely efficient power supply with smaller MOSFETs, fewer passives and discrete components, and a lower-cost transformer.

[ HiperTFS ] also includes a 20 W flyback standby controller and MOSFET based on the highly popular [ TinySwitch ]a" technology used in billions of power converter ICs due to its simplicity of operation, light load efficiency, and rugged, reliable, performance.

Comments David New,product marketing managerat Power Integrations: a[ HiperTFS ]enables engineers to build power supplies that cost-effectively meet current and emerging power efficiency standards, such as 80 PLUS^® Bronze for PCs and the new mandatory California Energy Commission efficiency regulations for televisions. With its high level of integration, supported by comprehensive design software, [ HiperTFS ]simplifies design efforts and enables engineers to quickly develop high-power power converters. We have brought the advantages of integration to applications below about 50 W for many years; now, high-power products can also benefit from the simplicity, reliability, compactness, and cost savings of a single-chip approach.a

[ HiperTFS ]productsinclude Power Integrationsa™ standard set of comprehensive protection features, such as integrated soft-start, fault and over-load protection, and hysteretic thermal shutdown. [ HiperTFS ]devices are available now in PIa™s popular, grounded-tab, eSIP-12 power package and are priced from $2.38 each for 10,000-piece quantities. The product datasheet, design ideas, and introductory video are available now on the Power Integrations website at [ www.powerint.com/hipertfs ].
