Abstract
A voltage regulator system of an information handling system includes a Smart Power Stage (SPS) and a voltage regulator controller. The SPS includes a high-side transistor and a low-side transistor. The voltage regulator controller detects a normal power down of the information handling system and sets bleed state for the SPS to a first state. Based on the bleed state being set to the first state, the voltage regulator controller provides a first control voltage to the low-side transistor and a second control voltage to the high-side transistor. The first control voltage causes the low-side transistor to be fully turned on, and the second control voltage causes the high-side transistor to be in a linear region. In response to a predetermined amount of time expiring, the voltage regulator controller enters the SPS in an idle mode.
