Application 2: 18 - 50 V Input, 16 V at 1 A Output
This is an example of using the TPS40200 in a higher voltage application. The output voltage is 16 V at 1 A with
an 18 to 50 V input. Module boards built to this schematic and a test report are available from the factory. Some
of the test results are shown below.
Test Results
The following two curves demonstrate some of the performance obtained from this application. Further
information and support material is available from the factory.
