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

Output Load Transient
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.
