AG奔驰宝马多人版Power Integrations’ High-Frequency Two-Switch-Forward IC Slashes System Cost and Footprint
SAN JOSE, Calif.--(BUSINESS WIRE)-- Power 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.
AG奔驰宝马多人版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.
AG奔驰宝马多人版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.”
AG奔驰宝马多人版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.
