Abstract: 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.

Abstract: Aspects include a hold-up capacitor charging circuit for a power supply. The hold-up capacitor charging circuit includes a voltage boosting charge pump circuit with a hold-up capacitor electrically coupled to a voltage source. The hold-up capacitor charging circuit also includes a fly-back circuit. The fly-back circuit includes a transformer with a primary winding electrically coupled to the voltage source and a secondary winding electrically coupled to a load. A switch is electrically coupled to the primary winding and the voltage boosting charge pump circuit. A controller is operable to open and close the switch to control energy transfer from the primary winding to the secondary winding and charge the hold-up capacitor responsive to voltages of the voltage source, the voltage boosting charge pump circuit, and a reflected voltage of the secondary winding at the primary winding.

Abstract: In accordance with one or more embodiments, a monostable multivibrator that is communicatively coupled to a host device and an external analog-to-digital converter is provided. The monostable multivibrator receives a chip select signal from the host device. The monostable multivibrator also generates, in response to the chip select signal, a conversion start signal to the external analog-to-digital converter.
