To operate the LM3553 1.2A Dual Flash LED Driver System with I2C Compatible Interface, connect a supply voltage (2.7V-5.5V) between board connectors VIN and GND and attach an I2C interface using one of the methods described in the EXTERNAL CONTROL INTERFACE SECTION of this document.

This circuit is designed to replace a dual-filament incandescent bulb in a combined brake/tail light for automotive use. When power is applied to the 'Tail' input the current in the LED is regulated to 300mA. When power is applied to the 'Brake' input or both inputs simultaneously, the current in the LED increases to 900mA. The 'Brake' and 'Tail' input voltage can vary between 8V and 40V This makes the circuit suitable for standard passenger cars...

The LM3485 design is a buck regulator derived controlled current source designed to drive high power, high brightness LEDs (HBLEDs) at a constant current of 1.0A. The design can accept an input voltage ranging from 5V to 30V and can control the output current delivered to series and/or parallel arrays of HBLEDs as long as the forward voltage of all the LEDs in series is less than 0.9 x Vin. The accuracy of the output current is +-10%.
