Pin Function
1
PGND
Power ground. Electrically needs to be connected to AGND.
2
VIN
Supply voltage input. When VIN rises above the UVLO threshold the device starts up.
3
AGND
Reference connection for controller section. Also used as thermal connection for controller
section. Electrically needs to be connected to PGND.
4
FB
LED Current Feedback Input. The FB voltage is regulated at 250mV in normal operation. The FB
sense resistor sets the nominal LED current
5
COMP
External loop compensation pin.
6
EN
The enable pin is active high. Connect EN pin to VIN if not used. Do not leave the EN pin floating.
7,8
LX
PWM output connection to inductor. Thermal connection for output stage.
