HiperPFS™-2
IC incorporates high-efficiency controller, MOSFET and boost diode;
saves space, increases reliability, reduces costs
SAN JOSE, Calif.--(BUSINESS WIRE)--
Power
Integrations (Nasdaq: POWI),
the leader in high-voltage integrated circuits for energy-efficient
power conversion, today introduced HiperPFS-2,
a new family of high-efficiency, active-PFC ICs for offline
applications from 100 W to 380 W. HiperPFS-2
ICs combine a boost PFC controller, driver, PFC power MOSFET, PFC diode
and protection circuits in one package, enabling exceptionally compact
designs ideal for small-form-factor power supplies as used in mini-tower
PCs, all-in-one PCs, game console adapters and TVs.
The HiperPFS-2
controller uses a variable-frequency CCM algorithm providing up to 97%
efficiency across the load spectrum from 20% to 100% and power factor
greater than 0.9 at 20% load with 265 VAC input for designs over 200 W.
Including line-connected sense elements, the new device contributes just
60 mW to a typical high-power adapter’s 300 mW no-load budget. Conducted
and radiated EMI are minimized due to the integrated soft-recovery diode
and short parasitic inductance loop which results from the highly
integrated, compact design.
Comments
Edward Ong
, product marketing manager for Power
Integrations: “The HiperPFS-2
device is the most highly integrated PFC solution available. This
enables designers to cost-effectively meet the 80 PLUS® Gold and
Platinum efficiency standards in space-constrained PCs. The device’s
excellent no-load performance simplifies design and reduces cost in
high-power adapter applications targeting aggressive standby or no-load
specifications.”
Key applications for HiperPFS-2
ICs include TVs, PCs, game console adapters, telecoms and industrial
products such as blowers, motor drives and chargers. A new reference
design based on the HiperPFS-2
IC, DER-294,
describes a 350 W output power boost CCM PFC board with wide range AC
input. DER-294
is able to attain > 97% efficiency for 230 VAC across a wide load range
and > 0.9 PF at 20% load- see http://www.powerint.com/sites/default/files/PDFFiles/der294.pdf.
HiperPFS-2
devices are sampling now in two of Power Integrations’ innovative
eSIP-16 packages: the standard eSIP16-D (H package) and the L-bend
eSIP16-G (L package) for low-profile applications. Both feature an
isolated metal heatsink pad for simple and easy mounting. HiperPFS-2
family devices are priced from $0.959 each in 10K quantities.
