Power Integrations Launches InnoSwitch3, a 94%-Efficient Offline Flyback Switcher IC Family

New InnoSwitch™3 integrated switcher ICs cut losses by 25%, deliver
constant efficiency over a wide range of line and load conditions

SAN JOSE, Calif.–(BUSINESS WIRE)–#Charger–Power Integrations (Nasdaq: POWI),
the leader in high-voltage integrated circuits for energy-efficient
power conversion, today announced the release of its InnoSwitch™3
family of offline CV/CC flyback switcher ICs. The new devices achieve up
to 94% efficiency across line and load conditions, slashing power supply
losses by a further 25% and enabling the development of compact power
supplies up to 65 W without heatsinks. InnoSwitch3 devices are ideal for
power supplies with challenging energy consumption, footprint or thermal
constraints, particularly those targeting mandatory Total Energy
Consumption (TEC) specifications.

The InnoSwitch3 IC family is optimized into three application-specific
series:

• CE: Current External. Includes accurate CC/CV regulation with
  external output current sense for optimum design flexibility. Targets
  compact single-voltage chargers, adapters, IoT and building automation.
• CP: Constant Power. Ideal for USB Power Delivery (PD), rapid
  charging and other applications where a dynamic output voltage is
  required.
• EP: Embedded Power. Features the family’s highest-rated MOSFET
  (725 V) and provides full line and load protection with excellent
  multi-output cross-regulation for demanding industrial applications
  and appliances.

These newest flyback switcher ICs employ Power Integrations’ innovative
isolated digital communications technology, FluxLink™,
plus synchronous rectification, quasi-resonant switching and a precise
secondary-side feedback sensing and control circuit. This results in
highly efficient, accurate, reliable power supply circuits without the
need for optocouplers. InnoSwitch3 devices are CCC, UL and VDE
safety-certified to bridge the isolation barrier, and the InSOP™-24
package provides a low-profile, thermally efficient solution with
extended 11.5 mm creepage and clearance between primary and secondary
sides for high reliability, surge and ESD robustness. The new devices
also incorporate a host of protection features, including lossless line
overvoltage and under-voltage, output overvoltage, over-power,
over-current and over-temperature protection, as well as output
rectifier short-circuit protection. Device sub-families are provided
with either latching or auto-recovery capability, according to the
typical demands of each target application space. All InnoSwitch3 ICs
feature on-board high-voltage MOSFETs (rated at 650 V for the CP and CE
series and 725 V for the EP series).

Comments Mike Matthews, VP of product development at Power Integrations:
“InnoSwitch3 ICs represent a new state of the art in flyback power
supply design. These new devices surpass the previously unrivaled
efficiency of our InnoSwitch products, reducing losses by a further 25%
and delivering the highest available efficiency across all line and load
conditions. With unmatched system simplicity and low component count,
InnoSwitch3 ICs enable exceptionally compact, reliable power supplies
for a vast range of applications.”

InnoSwitch3
ICs target adapters and open-frame power supplies for consumer,
computer, communication and industrial applications. InnoSwitch3-CP and
InnoSwitch3-CE IC samples are available now, priced at $1.11 (CE) and
$1.15 (CP), in 10,000-piece quantities. InnoSwitch3-EP parts will be
available in November 2017 at $1.18 per 10,000-pieces. An online
selection tool, Build Your Own InnoSwitch, is available to help
designers customize device features for their particular design
specifications. Technical support for InnoSwitch3 ICs, including the PI
ExpertTM Online design tool, is available from the Power
Integrations website at www.power.com/products/innoswitch/.
