Abstract
A control circuit for a voltage regulator has an energy regulation circuit and a switching control circuit. The energy regulation circuit provides a regulation signal based on an output voltage, an output current, and a maximum energy reference. The maximum energy reference decreases with increasing of an ambient temperature and increases with decreasing of the ambient temperature. The switching control circuit provides a switching control signal based on the regulation signal to turn ON and turn OFF at least one switch of a plurality of switches of the voltage regulator, such that the output voltage and the output current satisfy a first relationship when the ambient temperature equals a first temperature value, and the output voltage and the output current satisfy a second relationship when the ambient temperature equals a second temperature value.
