Page 2: Introduction
1.1 Description The TPS40075EVM-001 is designed to use a regulated 12-V bus (between 10 V and 14 V) to produce a high current, regulated 1.5-V output at up to 15 A of load current. The TPS40075EVM-001 is design to demonstrate the TPS40075 in a typical regulated bus to low-voltage application while providing a number of test points to evaluate the performance of the TPS40075 in a given application. -

Page 5: Adjusting Output Voltage (R5 And R6)
R6 to generate popular output voltages with R5 open R5 can be used to increase the accuracy that can be obtained without using more expensive resistors. The TPS40075EVM-001 is stable through these output voltages but the efficiency can suffer as the power stage is optimized for the 1.5-V output. -

Page 10: Evm Assembly Drawings And Layout
Figure 6-6 show the design of the TPS40075EVM-001 printed circuit board. The EVM has been designed using a 4-layer, 2-oz. copper-clad circuit board 3.0 inch × 3.0 inch with all components on the top side to allow the user to easily view, probe, and evaluate the TPS40075 control device in a practical application. -
