Abstract
Circuits for regulating and/or controlling integrated circuits such as drivers and switching regulators generally include a first switch configured to control or regulate a current, voltage drop or voltage boost; a first regulator or driver configured to transmit first pulses to the first switch, the pulses having a first pulse width; and pulse width modulation circuitry configured to (i) reduce the first pulse width when a first thermal threshold is met and (ii) increase the first pulse width when a second thermal threshold is met, the second thermal threshold being less than the first thermal threshold.
