Power Integrations Launches InnoSwitch3, a 94%-Efficient Offline Flyback Switcher IC Family
2017-09-12 | ReturnThis Smart News Release features multimedia. View the full release here: http://www.businesswire.com/news/home/20170912006528/en/
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.
