STMicroelectronics SRK2001A Controller
STMicroelectronics SRK2001A Controller features a control scheme for secondary side synchronous rectification in LLC resonant converters. The controllers provide two high-current gate drive outputs, each capable of directly driving N-channel power MOSFETs. Each gate driver is controlled separately, and an interlock logic circuit prevents the two synchronous rectifier MOSFETs from conducting simultaneously.
