METHOD FOR IMPROVING VOLTAGE IDENTIFICATION TRANSIENT RESPONSE AND VOLTAGE REGULATOR |
摘要 |
An exemplary method for improving voltage identification (VID) transient response is adapted to a voltage regulator and includes steps of: continuously sensing an inductor current of the voltage regulator to thereby output a current sense signal; during a steady state operation period, sampling the current sense signal to thereby obtain a sampling result for providing a droop control signal; after entering a VID transient period from the steady state operation period, holding the sampling result for providing the droop control signal; and taking the droop control signal as a consideration factor of producing a pulse width modulation signal to regulate an output voltage of the voltage regulator.
