A loss of the voltage regulating circuit is reduced and a utilization rate of power supply is improved by acquiring the electrical parameters at different preset switching frequencies, determining corresponding efficiencies of the voltage regulating circuit, and controlling the power tube to take the preset switching frequency corresponding to the highest efficiency as the working frequency.

A power delivery system is described that enables instant 20V/28V power delivery to sink devices by utilizing unique Configuration Channel (CC) resistor signatures to bypass standard power negotiation delays. The system may implement non-standard pull-down resistors (Rd) in sink devices and matching unique pull-up resistors (Rp) in source adapters to create CC voltages outside legacy USB PD specification ranges, instantly signaling full-power capability without traditional multi-step negotiations. Upon detecting such compatible unique signatures, the source may immediately apply a VBUS voltage of 20V or 28V at full current, eliminating the boot delays caused by standard USB PD negotiation processes. The system also avoids problematic sink standby (pSnkStdby) power consumption limitations that prevent dead battery boot scenarios. The system maintains backward compatibility through automatic fallback to standard USB PD negotiation when non-compliant devices are connected.
