Supply voltage pin. Supply voltage range : 2.8V to 5.5V
Input pin for IC ON/OFF control and variable LED I
0 to 0.5V : Shutdown Mode (IC shutdown)
1.0V to 2.5V : I
Over 2.5V : I
PWM signal input for IF control (see p.5)
This pin must be set to a certain logic level, as unstable output could result if the pin is left
open.
No Connection or Connected to GND
DC/DC converter switching pin – switch incorporates N-ch MOSFET
Ground pin
LED IF setting resistor connecting terminal.
