Application 2: 18-V to 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-V to 50-V input. Module boards built to this schematic, and a test report, are available from the factory.
The following shows some of the test results.
