  • Adaptive gate drive for a power switch transistor in a switching power converter
    Patent number: 11689095
    Abstract: A gate drive control circuit is provided that charges a gate voltage of a power switch transistor during a power switch transistor on-time period. During a first portion of the on-time period, the gate drive control circuit charges the gate voltage through a relatively-low resistance. During a second portion of the on-time period, the gate drive control circuit charges the gate voltage through a relatively-high resistance. Finally, during a third portion of the on-time period, the gate drive control circuit charges the gate voltage through another relatively-low resistance.
