DIM
CS
EP
Digital PWM Dimming Input
Current-Sense Input. CS is the current-sense input for the switching regulator and is
also connected to the source of the internal power MOSFET. Connect a sense resistor
from CS to PGND to set the switching current limit.
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
contiguous ground plane for effective power dissipation. Connect EP to SGND.
Do not use as the only ground connection.
