Overview
The STSR30D-TR is a low-side gate driver IC manufactured by STMicroelectronics. It is designed to drive N-channel MOSFETs in a non-inverting configuration, particularly for use in synchronous rectifier applications in high-efficiency flyback converters. The IC provides high current outputs to drive secondary power MOSFETs, ensuring efficient operation and preventing shoot-through conditions. It features a fast cycle-after-cycle logic control mechanism synchronized by a clock signal, along with an inhibit function to shut off the drive output during discontinuous mode conditions. The device also includes a disable pin to reduce overall current consumption during no-load conditions.
