DESCRIPTION
Tie to higher than 1.5V to enable device, 0.3V or less to disable device.
Reference voltage is 95mV. Connect cathode of lowest LED and
resistor here. Calculation formula: RFB=95mV/ILED
Connect inductor/diode here. Minimize trace area at this pin to reduce
EMI.
Bypass VIN to GND with a capacitor sitting as close to VIN as possible.
The internal MOSFET will turn off when VOUT >27V.
