NAME
DESCRIPTION
1
GND
Ground Pin. Connect to local ground.
2
VIN
Input Supply Pin. Connect to the input supply voltage, the inductor and the input supply decoupling capacitor.
3
PWM/EN
PWM or Enable Pin. Connect external PWM signal allows pulse width modulation current operation. Enable
signal allows peak current operation or disable signal shuts down the device.
4
NC
No Connect
5
FB
Feedback Pin. Connect the sense resistor between FB and ground. The cathode of bottom LED can also
be connected at this pin if the output current is not to be PWMed.
6
FBSW
FB Disconnect Switch. Connect to the cathode of the bottom LED if the output current to be PWMed.
7
VOUT
Output Pin. Connect to the anode of the top LED and the output filter capacitor.
8
LX
Switching Pin. Connect to inductor.
