Description
The TPS51727EVM is designed to use a regulated 12-V (8-V to 14-V) bus to produce a high-current,
regulated 1.5 V or 4-bit digital-to-analog converter (DAC) with a 0.875-V to 1.25-V output range at up to 40
A of the load current. The TPS51727EVM is designed to demonstrate the TPS51727 in a typical,
low-voltage application while providing a number of test points to evaluate the performance of the
TPS51727.
