TPS92667-Q1 evaluation module for LED matrix managers


Order now


The TPS92667-Q1 evaluation module features the TPS92667-Q1 and TPS92665-Q1 16-channel matrix manager devices. The EVM kit contains three PCBs and associated cabling to provide and end-to-end power solution for a typical matrix headlight system. The PSIL243 PCB contains one TPS9265-Q1 device and three TPS92667-Q1 devices which provide pixel level control of 64 total LEDs. The PSIL215 PCB contains the power stage comprised of a TPS92682-Q1 multi-phase boost voltage pre-regulator followed by two TPS92520-Q1 dual channel synchronous LED drivers to provide four total current source outputs to the matrix LED load. The PSIL132 PCB provides the MSP432 microcontroller and peripherals to control the system from a laptop computer.
