TPS62366AEVM-757
This user’s guide describes the characteristics, operation, and use of the Texas Instruments TPS62366A
evaluation module (EVM). This EVM is designed to help the user easily evaluate and test the operation
and functionality of the TPS62366A. The EVM converts a 2.5-V to 5.5-V input voltage to a regulated
output voltage that delivers 4 A. The output voltage is programmable via the I2C interface in 10-mV steps
between 0.5V and 1.77V. This user’s guide includes setup instructions for the hardware, printed-circuit
board layouts for the EVM, a schematic diagram, a bill of materials, and test results for the EVM.
