PIN
SOT23-6
DESCRIPTION
LX
1
Switch Pin. Connect inductor/diode here. Minimize trace area at this pin to reduce EMI.
GND
2
Common Ground
FB
3
Feedback Pin. Reference voltage is 0.25V. Connect cathode of lowest LED and resistor
here. Calculate resistor value according to the formula: RFB=0.25/ILED
EN
4
Chip Enable Pin. Connect to 1.4V or higher to enable device, 0.3V or less to disable
device.
IN
6
Input Supply Voltage
OUT
5
Overvoltage Sense. When VOUT is greater than 27V, the internal N-channel MOSFET turns
off until VOUT drops below 25V, then the IC reenters start. Connect a 1uF capacitor from
OUT to GND.
