Description for the TPS61310EVM-638
The TPS61310EVM-638 Evaluation Module (EVM) demonstrates the Texas Instruments TPS61310 LED camera flash and video light driver with I2C interface. The user’s guide describes the characteristics, functions, and use of the TPS61310EVM-638 Evaluation Module This document includes setup instructions, a schematic diagram, a bill of materials and PCB layout drawings for the EVM. The TPS61310 is an integrated system with a broad feature set for driving up to three LEDs for still-camera flash and video-camera lighting applications. The power stage is capable of supplying a maximum total current of up to 1600mA (2×400mA for LED1 and LED3, 800mA for LED2). The device operates as an single, dual or triple channel LED driver generating the required LED forward voltages. The internal step-up converter boosts the input voltage adjusted to the required LED forward voltage and controls the LED current with the integrated current sinks. The internal step-up converter can be used for further applications as well, such as supplying an audio amplifier. All functions and feature sets can be either addressed by dedicated hardware pins or with the I2Cinterface.
