Follow these procedures when configuring the EVM for testing.
CAUTION: Many of the components on the TPS62120EVM-640 are susceptible to damage by electrostatic discharge (ESD). Customers are advised to observe proper ESD handling precautions when unpacking and handling the EVM, including the use of a grounded wrist strap, bootstraps, or mats at an approved ESD workstation. An electrostatic smock and safety glasses should also be worn.
- Work at an ESD workstation. Make sure that any wrist straps, bootstraps, or mats are connected and reference the user to earth ground before power is applied to the EVM. Electrostatic smock and safety glasses should also be worn.
- Connect a dc power supply between J1 and J3 on the TPS62120EVM. Note that the input voltage should range from 2.0 V to 15 V. Keep the wires from the input power supply to EVM as short as possible and twisted.
- Connect a dc voltmeter or oscilloscope to the output sense connection (J5) of the EVM.
- A load of up to 75 mA can be connected between J4 and J6 on the TPS62120EVM.
- To enable the converter, connect the shorting bar on JP1 between EN and ON on the TPS62120EVM.
