Operation

•

Connect a 0-A to 100-mA load between an OUT pin at connector J4, and a GND pin at connector J3.

Disable the output by connecting the jumper on JP1 from the EN pin to the OFF pin.

Operation

•

Turn on the input power supply. For initial operation, set the input power supply, VIN – J1, to 10 V

Enable the output by reconnecting the jumper on JP1 from the EN pin to the ON pin.

Vary the respective loads and VIN voltages as necessary for test purposes.

Test Results

This section provides typical performance waveforms for the TPS7A1601EVM-046 printed-circuit board.

4.1 Turnon Sequence

Figure 1 shows the turnon/off characteristic where VIN is preset to 10 V, the output drives full load, and

the EN turnon is stepped to 10 V (C2, red). The output soft start (C1, yellow) shows a monotonic rise time

of approximately 60 ms. The output voltage start-up ramp is not load dependant.

4.2 Output Load Transient

Figure 2 shows the load transient response (OUT – C1, yellow) for a full-load step transient from 10 mA to

100 mA (C4, green). VIN is set at 10 V.
