Product Details

The InnoSwitch™5-Pro family of ICs 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. InnoSwitch5-Pro ICs achieve zero voltage switching in discontinuous conduction mode using advanced SR FET control. 

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.
