In order to understand the functions performed by the PIP201-12M, 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
When the input voltage is LOW and current is flowing in the inductor, the upper
MOSFET must be off and the lower MOSFET must be on. Current flows from the
power ground (V
output.
Finally, when switching between states, both MOSFETs must not be on at the same
time.
