Power Integrations’ High-Frequency Two-Switch-Forward IC Slashes System Cost and Footprint

Higher switching speed and increased integration yield smaller magnetics, reduce component count

SAN JOSE, Calif. — (BUSINESS WIRE) — November 12, 2013Power Integrations (Nasdaq: POWI), the leader in high-voltage integrated circuits for energy-efficient power conversion, today announced the HiperTFS™-2 family of ICs, combining two-switch-forward and flyback power-supply controller ICs with integrated high-voltage MOSFETs. This high level of integration saves more than 20 components, resulting in a smaller form factor and higher power density. The main converter provides a selectable switching frequency between 66 kHz and 132 kHz, which reduces system cost by enabling the use of very small magnetics.

HiperTFS-2 ICs enable efficiencies of more than 90% at full load. They also provide 175% peak power, a requirement of next-gen Intel CPUs. This single-chip implementation of a two-switch-forward main (66/132 kHz) and flyback (132 kHz) standby power supply delivers up to 364 W total output power (586 W peak) in a compact, two-row eSIP™ power package. Safety features include undervoltage, overvoltage, over-temperature, overcurrent and short-circuit protection. A transformer-reset control function prevents saturation under all conditions.

Comments Chris Lee, product marketing manager at Power Integrations: “ HiperTFS-2 ICs enable power supply miniaturization in applications including 80 PLUS® Bronze and 80 PLUS® Silver PCs, gaming-console adapters and industrial products. The inclusion of the high-side MOSFET driver allows designers to eliminate the pulse transformer and many other supporting components, simplifying design and reducing the size (and cost) of the magnetics.”

A new reference design based on the HiperTFS-2 IC, DER368, describes a 12 V, 180 W power supply with 250 W peak power load and 10 W standby power - see http://www.powerint.com/sites/default/files/PDFFiles/der368.pdf. HiperTFS-2 IC samples are available now, and cost $1.74 each in 10K quantities.
