Pin Functions

PIN		TYPE⁽¹⁾	DESCRIPTION
NUM	NAME	TYPE⁽¹⁾	DESCRIPTION
1	C1P	A	Positive pin for charge pump flying capacitor. If feature is disabled, the pin may be left floating.
2	C1N	A	Negative pin for charge pump flying capacitor. If feature is disabled, the pin may be left floating.
3	VDD	P	Input voltage pin for internal circuit.
4	SQW	A	Square wave output. Can be used for generating extra voltage rail. If unused, the pin may be left floating.
5	VSENSE_N	A	Pin for input current sense.
6	VSENSE_P	A	Pin for OVP/UVLO protection and input current sense.
7	ISET	A	Optional resistor for setting LED maximum current. If feature is disabled, the pin may be left floating.
8	TSENSE	A	External temperature sensor for LED current control. If feature is disabled, the pin may be left floating.
9	FILTER	A	Low pass filter for PLL. If feature is disabled, the pin may be left floating.
10	SGND	G	Signal ground.
11	FAULT	OD	Fault signal output. If unused, the pin may be left floating.
12	SYNC	I	Input for synchronizing boost. This pin must be connected to GND if not used.
13	VSYNC	I	Input for synchronizing PWM generation to display refresh. This pin must be connected to GND if feature is disabled.
14	MISO	O	Slave data output (SPI). If unused, the pin may be left floating.
15	MOSI/SDA	I/O	Slave data input (SPI) or serial data (I²C). This pin must be connected to GND if not used.
16	SCLK/SCL	I	Serial clock for SPI or I²C. This pin must be connected to GND if not used.
17	NSS	I	Slave select (SPI mode) or fault reset (I²C or standalone mode). This pin must be connected to GND if not used.
18	PWM	I	PWM dimming input. This pin must be connected to GND if feature is disabled.
19	VDDIO/EN	I	Enable input pin and reference voltage for digital pins.
20	IF	I	Interface selection: low – I²C or standalone mode; high – SPI.
21	OUT4	A	LED current sink output. If unused, the pin may be left floating.
22	OUT3	A	LED current sink output. If unused, the pin may be left floating.
