FUNCTIONAL PIN DESCRIPTIONS
Pin
Function
Description
1
Enable
The device is enabled with a positive voltage signal at this pin. The enable controls both channels.
2
Dim
This pin is used for analog or PWM dimming control. An analog signal of 0 – 3.3 volts is required, or a PWM
signal with an amplitude greater than 3.3 volts. The dim controls both channels.
3
N.C.
No connection.
4
Gnd
Ground Reference to the device.
5
Source1
Source terminal of the FET 1
6
Drain1
Drain terminal of the FET 1, which is also the switching node of the load 1.
7
Drain2
Drain terminal of the FET 2, which is also the switching node of the load 2.
8
Source2
Source terminal of the FET 2
9
Vcc
Input voltage to the LED driver. This voltage is compatible with any battery based systems of up to 6 V.
