f) PWM Driver For PVCC

To ensure the good power efficiency of the H-bridge driver, a Buck DC-to-DC converter may be used to

regulate the PVCC. The controller selects the peak voltage among the channels and used it to control

the duty cycle of the PWM. External components necessary are: PNP transistor, inductor coil, diode

and capacitors. The configuration of a Buck DC-to-DC converter is shown as follow:

g) Bypass Capacitor

To have prevent noise, a bypass capacitor (roughly 0.1 µF) is connected from PVCC pin to the GND pin

as close as possible.
