2 Introduction

The Texas Instruments LM3645EVM evaluation module (EVM) helps designers evaluate the operation and performance of the LM3645 High-Current LED driver. The device offers configurability via I2C-compatible interface. It can be enabled in Flash or Torch mode via the I2C interface or externally using the STR1, STR2, TORCH/TX, TEMP1 and TEMP2 pins. The module utilizes four LEDs (D1, D2, D3 and D4) mounted on the EVM.

The EVM contains one Synchronous Boost LED Flash Driver (See Table 2-1).
