TPS62743EVM-689: 1.2 ~ 3.3V @ 300mA, 2 ~ 5.5V in

Summary

This user’s guide describes the characteristics, operation, and use of the Texas Instruments TPS62743 evaluation module (EVM). This EVM is designed to help the user easily evaluate and test the operation and functionality of the TPS62743. The EVM converts a 2.0-V to 5.5-V input voltage to a regulated output voltage that is set between 1.2 V and 3.3 V at up to 300 mA. The TPS62743 has 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.

The TPS62743 is a 300-mA, synchronous, step-down converter in a tiny 1.6 x 0.9-mm, 8-ball DSBGA package. The output voltage is fixed inside the device by the connection of the three VSELx pins.

The TPS62743EVM-689 uses the TPS62743 device. The EVM operates with full-rated performance with an input voltage between 2.0 V and 5.5 V.
