Abstract
A method, system and computer program product for improving inductor current ramp down times in a DC-to-DC converter having an inductor conductively coupled to a low side transistor on a first side and an or-ing transistor coupled to a second side, where the DC-to-DC converter is in a phase redundant power supply. The method comprises turning off the low side transistor and turning off the or-ing transistor in response to an unloading transient.
