In one configuration, the input voltage is received as the voltage across respective drain-source nodes of a synchronous switch (low side switch) disposed in a power supply. The protection circuit selectively controls conveyance of the input voltage so that damaging transient voltages on the input voltage are not passed to a downstream sampling circuit. The sampling circuit includes a capacitor circuit to store the sample of the input voltage. During operation, the sampling circuit utilizes the input voltage conveyed by the input voltage circuit to charge the capacitor with a sample voltage representative of the current. Because the sampling circuit is protected from the damaging transient voltages via the protection circuit, the sampling circuit as well as other downstream circuitry can be fabricated from a type of transistors other than those used in the input voltage circuit to facilitate more accurate current calculations using a small sized capacitor to store the sample of the input voltage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Current sensing in a power supply","description":"During operation, a protection circuit receives an input voltage representative of current delivered by a power supply phase to a load.
