The Power Integration Clamp Zero series IC pairs with the InnoSwitch4 family of ICs to eliminate energy wasted due to switching losses in the clamp and primary switch. This dramatically improves power supply efficiency easily exceeding 95% while maintaining the flexibility and low component count of the flyback architecture. It incorporates a high-side power switch and level shifted self-biased controller which receives communication from a low-side transceiver connected to the InnoSwitch4 primary controller.
