Product Details

The InnoSwitch™4-Pro family of I²Cs substantially reduces the size of power adapters. Switching frequency of up to 140 kHz and a very high level of integration combine to reduce the component volume and PCB board area required by a typical adapter implementation.

InnoSwitch4-Pro interfaces seamlessly with the ClampZero family of active clamp ICs to achieve Zero Voltage Switching in both continuous and discontinuous conduction modes. Alternatively, InnoSwich4-Pro can operate in QR mode using an RCD clamp with the appropriated part number choice.

Overall system efficiency exceeds 95%, allowing designers to eliminate heat sinks, spreaders and potting materials for
thermal management, further reducing size, component cost and manufacturing complexity. The integration of PowiGaN primary switch and controller, isolated feedback and secondary controller with an I²C interface simplifies the development and manufacturing of fully programmable, highly efficient power supplies.
