Abstract:
This document discusses, among other things, apparatus and methods for an edge rate driver for a power converter switch. In an example, the driver can include an input node configured to receive a pulse width modulated signal, a first switch configured to couple a control node of the power converter switch to a supply voltage during a first state, a second switch configured to couple the control node of the power converter switch to a reference voltage during a second state, and a first current source configured to supply charge current to the first switch when the power converter switch transitions from the second state to the first state, the charge current configured to charge a parasitic capacitance of the power converter switch.
