Function Description
1
SHDN
Voltage-input terminal for IC-enable.
SHDN
= H → Operation Mode, SHDN = L → Shutdown Mode (IC shutdown)
Please do not open this terminal.
2
OVD
Over voltage detection terminal.
IC switching operation is disabled with detection over voltage.
If the voltage returns to detection level or less, operation is enabled again.
3
VIN
Supply voltage input terminal. (2.8 V to 5.5 V)
4
SW
Switch terminal for DC/DC converter. Nch MOSFET built-in.
5
GND
Ground terminal.
6
FB
LED IF setting resister connecting terminal.
