A power converter for providing power to a load includes a buck converter having a DC input and a DC output and that is configured to receive a DC voltage at the DC voltage input and provide DC output voltage at the DC output. The converter also includes a voltage monitor that monitors a voltage provided at the DC output and a selectively connectable transient suppression circuit connected across that DC output and connected to the voltage monitor. The selectively connectable transient suppression circuit includes a dissipation circuit and a suppression circuit switch connected in series with the dissipation circuit that controls charge dissipation from the DC output into the dissipation circuit based on the voltage monitor determining that the voltage across the DC output is above a threshold.

Low voltage buck regulator voltage regulation with reduced overshoot and settling time

Provided are embodiments for operating an autonomous mode change circuit for solenoid drivers. The embodiments include initiating an operation of a solenoid, and receiving a command to control the operation of the solenoid. The embodiments also include controlling, by a drive circuit, a switch coupled to the solenoid based at least in part on the command, and detecting at least one of a current or voltage of the solenoid, and subsequently controlling the operation of the solenoid based at least in part on the detection.
