TPS62740EVM-186: 1.8 ~ 3.3V @ 300mA, 2.2 ~ 5.5V in

Summary

The TPS62740EVM-186 (PWR186-001) uses the TPS62740 device. The EVM operates with full-rated performance with an input voltage between 2.2 V and 5.5 V.

The TPS62740 is a 300-mA, synchronous, step-down converter in a 2 x 3-mm, 10-pin SON package. The output voltage is fixed inside the device by the connection of the four VSELx pins.

The user’s guide describes the characteristics, operation, and use of the Texas Instruments TPS62740 evaluation module (EVM). This EVM is designed to help the user easily evaluate and test the operation and functionality of the TPS62740.

The EVM converts a 2.2-V to 5.5-V input voltage to a regulated output voltage that is set between 1.8 V and 3.3 V at up to 300 mA. The TPS62740 also includes a load switch and power good output, while having an ultra-low quiescent current of 360 nA. This user’s guide includes setup instructions for the hardware, a printed-circuit board layout for the EVM, a schematic diagram, a bill of materials, and test results for the EVM.
