Function Description
1
GD
MOSFET control pin for DC/DC converter.
2
VIN
Supply input pin for IC drive. Operating voltage: 4.5 to 5.5V.
3
SHDN
Input IC enable signal.
SHDN="H" : Normal mode.
SHDN="L”: Power saving mode. IC stops.
4
PWM
Input ON/OFF control signal of constant current output pin (FB1 to 6).
LED current (IF) can be controlled by inputting PWM signal.

5
FB1
Constant current synchronization.
6
RSENS1
Constant current set resistor for sync driver (FB1).
7
FB2
Constant current synchronization.
8
RSENS2
Constant current set resistor for sync driver (FB2).
9
FB3
Constant current synchronization.
10
RSENS3
Constant current set resistor for sync driver (FB3).
11
RSENS4
Constant current set resistor for sync driver (FB4).
12
FB4
Constant current synchronization.
13
RSENS5
Constant current set resistor for sync driver (FB5).
14
FB5
Constant current synchronization.
15
RSENS6
Constant current set resistor for sync driver (FB6).
16
FB6
Constant current synchronization.
17
OVP
Over voltage detection. IC switching operation is disabled with detection over voltage. When
the voltage returns to detection level or less, operation is enabled again,
In case SHDN is input H and PWM is input L, output voltage is kept over 20V (typ) by
monitoring OVP voltage.
18
IS
Monitoring MOSFET current.
19
SS
When SHDN is input low to high, the constant number to limit the current is determined.
VOUT rising time changes depending on the constant number of Capacitor.
20
AGND
Ground pin for analog.
