Abstract
A power controller having good transient performance and including a voltage regulator and one or more (K) transient recovery circuits is described. The voltage regulator receives a supply voltage and generates a regulator output signal used to generate K output voltages for K loads. Each transient recovery circuit detects for transients in a respective output voltage and corrects the detected transients. In one design, the transient recovery circuit compares the output voltage against a low threshold voltage, detects a low transient when the output voltage is below the low threshold voltage, and couples the output voltage to a high voltage to correct the low transient. Alternatively or additionally, the transient recovery circuit compares the output voltage against a high threshold voltage, detects a high transient when the output voltage is above the high threshold voltage, and couples the output voltage to a low voltage to correct the high transient.
