Working Principle

The R2S12-0515/HP works by switching a high-efficiency synchronous rectifier between two power stages. During the first power stage, a MOSFET high-frequency switching operation is performed. The output voltage is controlled by the peak current of the MOSFET and the duration of the switching cycle. In the second power stage, a synchronous rectifier current is used to regulate the output voltage level. This is done by connecting the drain of the MOSFET to the source of the synchronous rectifier at a frequency determined by the duty cycle of the pulse-width modulation (PWM). The output voltage is then regulated by the peak current of the synchronous rectifier and the duration of the switching cycle.
