TPS62700EVM-264
This user’s guide describes the characteristics, operation, and use of the TPS62700EVM-264 and the
TPS62700EVM-264 evaluation module (EVM). This EVM demonstrates the Texas Instruments TPS62700
2-MHz, synchronous, step-down converter for power amplifier (PA) applications. The TPS62700 supplies
up to 650 mA of output current at a pin programmable output voltage between 1.3 V and 3.09 V from a
2.5-V to 6-V input source. This user’s guide includes setup instructions, schematic diagram, bill of
materials (BOM) and PCB layout drawings for the EVM.

The TPS62700EVM-264 evaluation module (EVM) helps designers evaluate the operation and
performance of the TPS62700 step-down converter. This converter is a 2-MHz, synchronous, step-down
converter that provides up to 650 mA of output current at a pin-programmable output for powering PA
applications. The board features the tiny 1,6-mm × 1,75-mm 8-ball WCSP package (YZF) for a small
solution size.
