US 2026/0095178 A1 · ADAPTIVE POWER SWITCH

Abstract

An example apparatus includes a plurality of switch circuit groups. Each switch circuit group includes a primary power switch circuit and a set of secondary power switch circuits. The apparatus includes a connection circuit that is configured to receive a first control signal from a control circuit and provide the first control signal to the plurality of switch circuit groups in a serial order. The plurality of switch circuit groups are configured to initialize based on the first control signal. The connection circuit is also configured to receive a second control signal from the control circuit and provide the second control signal in parallel to the switch circuit groups. Selected ones of the switch circuit groups are turned on and unselected ones of the switch circuit groups are turned off based on the second control signal.
