PIN FUNCTIONS

Pin #

Name

Description

LED1

Current source for LED1. Connect the anode of an LED to LED1.

A2/B2

OUT

Boost converter output.

A3/B3

Boost converter switching node.

A4/B4

PGND

Power GND.

LED2

Current source for LED2. Connect the anode of an LED to LED2.

TOR

Torch mode input signal.

Synchronization input signal for RF transmission signal. Pull TX low internally to float.

STR

Strobe signal input. STR synchronizes the flash pulse. Pull STR low internally to float.

VSS

Analog GND.

NTC

LED temperature detection. Connect NTC to GND with an NTC resistor when the NTC

function is used. Float NTC when not in use.

SDA

I2C interface data input.

SCL

I2C interface clock input.

Input supply. IN provides the power for the internal power and logic circuit. Bypass IN

locally.
