WiseWare® WI1001
WI1001 is a digital AC-DC controller optimized for wide bandgap (WBG) based SMPS. It is dedicated to controlling the …….. The controller is capable of operating the converter at high switching frequencies while ensuring ZVS operation for all the power transistors using a proprietary algorithm. The high frequency of operation enables to reduce the magnetic components size helping to further reduce the converter size, weight and thickness.
