Abstract
An isolated power chip based on wafer level packaging, including: an RDL-based micro-transformer, where a primary coil of the RDL-based micro-transformer is connected to a direct-current power supply and configured to output a direct-current voltage input by the direct-current power supply; a transmitting chip connected to the primary coil of the RDL-based micro-transformer, and configured to receive the direct-current voltage, convert the direct-current voltage into an alternating current signal, and transmit the alternating current signal to a secondary coil of the RDL-based micro-transformer; and a receiving chip connected to the secondary coil of the RDL-based micro-transformer, and configured to convert the alternating current signal into a direct-current signal, generate a control signal for stabilizing the output voltage according to a change of a load, and encode the control signal for digital isolation. The present disclosure further provides a method of manufacturing an isolated power chip based on wafer level packaging.
