Abstract
The GreenChip SR is a synchronous rectifier controller IC. It is capable of driving a synchronous rectifier switch in a Switched Mode Power Supply (SMPS). The circuit has a novel way of operation, which ensures fast turn-off of the synchronous rectifier switch. A smart blanking circuit prevents false detection due to ringing signals. It also contains additional circuitry for controlling the output voltage and current. The IC can directly drive an optocoupler. Furthermore, it has additional protection functions integrated.
