TPS62060EVM Test Data

5.2 Testing Procedure

Follow these procedures when configuring the EVM for testing.

CAUTION

Many of the components on the TPS62060EVM-663 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 also are recommended.

1. Connect a dc power supply between J1 and J3 on the TPS62060EVM. Note that the input voltage

must be between 2.7 V and 6 V. Keep the wires from the input power supply to the EVM as short as

possible and twisted.

2. Connect a dc voltmeter or oscilloscope to J5, the output sense connection of the EVM.

3. A load can be connected between J4 and J6 on the TPS62060EVM.

4. To enable the converter, connect the shorting bar on JP1 between EN and ON located on the

TPS62060EVM.

5. The TPS62060EVM has a feature to allow the user to switch between Power-Save mode under light

loads and forced PWM mode; this feature is enabled or disabled with jumper JP2.

Figure 3 through Figure 15 present typical performance curves for the TPS62060EVM. Actual

performance data can be affected by measurement techniques and environmental variables; therefore,

these curves are presented for reference and may differ from actual results obtained by some users.
