VDR2

Gate Drive Supply Bypass. The voltage at VDR2 is supplied from an internal regulator from

its respective VSP. VDR2 powers the internal circuitry and internal MOSFET gate drive for

SW2A and SW2B stage. Bypass VDR2 to AGND with a 0.1μF to 10μF capacitor.

30

VDR1

Gate Drive Supply Bypass. The voltage at VDR1 is supplied from an internal regulator from

its respective VSP. VDR1 powers the internal circuitry and internal MOSFET gate drive for

SW1A and SW1B stage. Bypass VDR1 to AGND with a 0.1μF to 10μF capacitor.

31

BST1B

Bootstrap Supply. BST1B powers the high-side gate of the SW1B stage. Connect a 0.1μF

or greater capacitor between BST1B and SW1B.

32

PGND1B

Power Ground of Channel 1B. Connect the exposed pad on the bottom side to the ground

plane.
