New offline flyback switcher chips deliver high efficiency for power supplies

RS Components has a new family of offline flyback switcher ICs from Power Integrations available offering efficiency of up to 94% and are ideal for use in state-of-the-art compact power supply designs. Aimed at the design of power supplies with stringent constraints regarding energy consumption, footprint and thermal performance, the new InnoSwitch3 family of offline CV/CC flyback switcher ICs achieve up to class-leading 94% efficiency over a wide range of varying line and load conditions. The family can also cut power supply losses by an additional 25% when compared to the past generation, allowing the development of small and lightweight power supplies that do not require heatsinks but can still handle up to 65W of power.
