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