PGND
Internal Switching MOSFET Drain Output
Internal Switching MOSFET Gate Input. Connect GATE to NDRV directly or through a
resistor to control the rise and fall times of the gate drive.
Power Ground. PGND is the high-switching current return path connection. Connect
SGND, LEDGND, and PGND at a single point.
Exposed Pad. EP is internally connected to SGND. Connect EP to a large-area
