1MHz 2.5A Buck DC/DC Converter
B. Short-Circuit and Over-Temperature Protection
1. Raise the input voltage to 5.5V.
2. Apply a short from V_O+ to GND at the evaluation board terminals.
3. Remove the short and verify that output returns to its initial value.
C. Enable Input and Power OK Output
1. Short the enable pin to GND. The output should decay to zero.
2. Remove the short applied to the enable pin. The output should recover to its initial value.
