TPS62750EVM-413
This user’s guide describes the characteristics, operation, and use of the TPS62750EVM-413 evaluation
module (EVM). This user’s guide includes setup instructions, schematic diagram, bill of materials, and
printed-circuit board (PCB) layout drawings for the EVM. The EVM features the 2.5-mm x 2.5-mm, 10-pin
SON package (DSK) on a 40-mm X 32-mm (1.6-inch x 1.2-inch) PCB.

The TPS62750EVM-413 evaluation module (EVM) helps designers evaluate the operation and
performance of the TPS62750 step-down converter. This EVM demonstrates the Texas Instruments
TPS62750 2.25-MHz, synchronous, step-down converter for power devices from USB or current-limited
inputs. The TPS62750 output is adjustable from 0.8 V to 85% of Vin, and the maximum Vin is 6 V. Output
current is determined by input, output voltage, and switch current limit of 1500 mA, but at 5 V in and 3.6 V
out the output current is up to 750 mA. Unique features of the TPS62750 is an adjustable input current
limit set by two onboard resistors. The Current Select jumper allows selection of a high- or low-input
current setting. The Enable jumper is provided to turn the device on and off.

negative connection to GND J3. Twist the leads to the input supply and keep them as short as possible to
minimize EMI transmission connection for the leads from the input source.

The two connectors are not installed, but if accurate measurements of the input or output are required, J2
or J5 can be installed for the measurements. Traces on the printed-circuit board (PCB) connect to the
input or output capacitor and run independent of the output and ground lines to the two connectors. Note
these traces are low current sense lines and must not be used as input or output.
