Abstract
This application relates to methods and apparatus for current monitoring in switched mode drivers. A switching driver has an output stage with a network of switches for switching an output node between different switching voltages and a modulator for controlling a duty-cycle of the switching output stage based on the input signal, where the modulator generates a modulator signal based on the input signal. A current monitor is configured to receive a first current signal indicative of a sensed first driver current and to determine and/or limit a second driver current using the first current signal and the modulator signal. One of the first driver current and the second driver current is an output current to the load and the other of the first driver current and the second driver current is an input current from a power supply.
