MULTI-REGULATOR POWER DELIVERY SYSTEM FOR ASIC CORES

摘要

An electronic product and method of operation are disclosed. The electronic product includes an application specific integrated circuit (ASIC) device having both a linear regulator module configured to be coupled to an optional external capacitance and a capless regulator module configured to be coupled to internal capacitance of the electronic product. Control logic of the ASIC device is responsive to a regulator selection signal for selecting one of the linear regulator module and the capless regulator module for use in powering the ASIC device. The control logic may select one of the linear regulator module or the capless regulator module for certain times of operation.
