Introduction
TPS40192EVM-001 is designed to use a regulated 12-V (8-V to 14-V) bus to produce a regulated 1.8-V
output at up to 10 A of load current. TPS40192EVM-001 is designed to demonstrate the TPS40192 in a
typical 12-V bus to low-voltage applications while providing a number of test points to evaluate the
performance of the TPS40192 in a given application. The EVM can be modified to support output voltages
from 0.9 V to 3.3 V by changing a single set resistor.
• Non-isolated, medium-current point of load and low-voltage bus converters
• Networking equipment
• Telecommunications equipment
• Computer peripherals
• Digital set-top box
• 8-V to 14-V input range
• 1.8-V fixed output, adjustable with single resistor
