Product Details

The ClampZero IC pairs with the InnoSwitch™4 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.

The ClampZero IC is an active clamping circuit which recycles otherwise wasted leakage inductance energy. The ClampZero 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.

By ensuring zero voltage switching across all line and load conditions and in both CCM and DCM operating modes, ClampZero combines with InnoSwitch4 to implement a highly flexible active clamp flyback solution. In a typical application paired with the InnoSwitch4 IC, the low switching losses permit use of a high switching frequency, minimizing the physical size of the transformer and resulting in an extremely small PCB footprint.
