In order to understand the functions performed by the PIP202-12M, consider the
requirements of a synchronous DC-to-DC converter output stage, driven from a PWM
controller
When the input voltage is HIGH, the upper MOSFET must be on and the lower
MOSFET must be off. Current flows from the supply (V
MOSFET and the inductor (L
