pin FuncTions (SSOP/QFN)

BG2, BG1 (Pins 16, 18/Pins 18, 20): Bottom Gate Drive.

Drives the gate of the bottom N-channel MOSFET between

ground and INTVCC.

PGND (Pin 17/Pin 19): Power Ground. Connect this pin

closely to the source of the bottom N-channel MOSFET, the

(–)terminalofCVCCandthe(–)terminalofCIN(Figure11).

INTVCC(Pin19/Pin21):Internal6VRegulatorOutput.The

driver and control circuits are powered from this voltage.

Bypass this pin to ground with a minimum of 4.7µF low

ESR tantalum or ceramic capacitor.

EXTVCC (Pin 20/Pin 22): External VCC Input. When EXT-

VCC exceeds 5.7V, an internal switch connects this pin to

INTVCC and shuts down the internal regulator so that the

controller and gate drive power is drawn from EXTVCC. Do

not exceed 7V at this pin and ensure that EXTVCC < VIN.

VIN (Pin 21/Pin 23): Main Input Supply. Bypass this pin

to SGND with an RC filter (1Ω, 0.1µF).
