DESCRIPTION
NUMBER
NAME
A1
SDA
I/O
Serial data connection for I2C-compatible interface.
A2
SCL
I
Serial data connection for I2C-compatible interface.
A3
SW
PWR
Inductor connection, diode anode connection, and drain connection for internal NFET. Connect
the inductor and diode as close as possible to SW to reduce parasitic inductance and capacitive
coupling to nearby traces.
B1
PWM
I
External PWM brightness control input and simple enable input.
B2
INT
O
Logic interrupt output signaling the ALS zone has changed.
B3
GND
Ground
C1
ALS2
I
Ambient light sensor input 2 with programmable internal pull-down resistor.
C2
HWEN
I
Active high hardware enable (active low reset). pull this pin high to enable the LM3530.
C3
IN
PWR
Input voltage connection. Connect a 2.7-V to 5.5-V supply to IN and bypass to GND with a 2.2-
µF or greater ceramic capacitor.
D1
ALS1
I
Ambient light sensor input 1 with programmable internal pulldown resistor.
D2
OVP
I
Output voltage sense connection for overvoltage sensing. Connect OVP to the positive terminal
of the output capacitor.
D3
ILED
PWR
Input terminal to internal current sink. The boost converter regulates ILED to 0.4 V.
