PRODUCTION DATA
A Schottky diode is required for all LM5012 applications to re-circulate the energy in the output inductor when the high-side MOSFET is off. The reverse breakdown rating of the diode should be greater than the maximum VIN plus a 25% safety margin, as specified in the Schottky Diode application section. The current rating of the diode must exceed the maximum DC output current and support the peak current limit for the best reliability. In this case, the diode carries the maximum load current.
