1.1 Typical Applications

This document outlines the operation and implementation of the TPS92520-Q1 as dual-synchronous buck constant current (CC) LED driver with the specifications listed in Table 2-1. For applications with a different input voltage range or different output voltage range, see the TPS92520-Q1 4.5-V to 65-V Dual 1.6-A Synchronous Buck LED Driver with SPI Control Data Sheet. The LEDMCUEVM-132 Development Tool controls the TPS92520EVM-133 evaluation board. The LEDMCUEVM-132 is available on TI website. Alternatively, any SPI controller board can control the TPS92520EVM-133. After the LED MCU EVM board is obtained from the TI website, the board must be programmed according to the instructions provided in this design guide. The program instructions are provided in Section 5.
