A voltage regulator having a multiple of main stages and at least one accelerated voltage regulator (AVR) bridge is provided. The main stages may respond to low frequency current transients and provide DC output voltage regulation. The AVR bridges are switched much faster than the main stages and respond to high frequency current transients without regulating the DC output voltage. The AVR bridge frequency response range can overlap with the main stage frequency response range, and the lowest frequency to which the AVR bridges respond may be set lower than the highest frequency to which the main stages respond.

Trans-inductor voltage regulator for high bandwidth power delivery

A power supply system, which has a switched-tank converter with an adjustable conversion ratio, includes a first-stage power converter, a second-stage power converter, and a controller. The first-stage power converter converts a supply voltage to a first output voltage, and modulates the first output voltage according to a modulation signal. A second-stage power converter converts the first output voltage to a second output voltage, and generates a power signal according to the output power of the second output voltage. The controller determines, according to the power signal, whether the output power exceeds a threshold to generate the modulation signal.
