Functional description
7.1 Basic functionality
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 (Figure 3).
When the input voltage is HIGH, the upper MOSFET must be on and the lower
MOSFET must be off. Current ows from the supply (VDDO), through the upper
MOSFET and the inductor (Lout), to the output.
