INN4477F - H341

4 - Pro InnoSwitch ™ series I squared C can significantly reduce the size of the power adapter.Up to 140 KHZ switching frequency combined with a high level of integration, can reduce the components required for the typical adapter package size and PCB area.

With ClampZero InnoSwitch4 - Pro series active clamp IC smooth docking, in continuous and discontinuous conduction mode to achieve zero voltage switching.Or you can choose the appropriate InnoSwich4 - Pro product series devices, using RCD clamp implement QR work mode.

Overall system efficiency more than 95%, and enables designers to eliminate thermal management needs of the heat sink, thermal conductivity and potting material, thus further reducing size, lowering the cost of components and the complexity of manufacturing.PowiGaN primary switch and feedback controller, isolation and secondary controller and I squared C interface integration simplifies the development and manufacturing of CNC high efficiency power supply.
