6.3.3 AVIN and PVIN Pins
The TPSM8D6C24 allows for a variety of applications by using the AVIN and PVIN pins together or separately. The AVIN pin voltage supplies the internal control circuits of the device. The PVIN pin voltage provides the input voltage to the switching power stage. When connected to a single supply, the input voltage for AVIN and PVIN can range from 4 V to 16 V. If the PVIN is connected to a separate supply from AVIN, the PVIN voltage can be 2.95 V to 16 V. If PVIN is connected to the same supply as AVIN, then AVIN has to meet a 4-V minimum and 16-V maximum to drive the controller and driver.
