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

Power Integrations 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.

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."
