摘要： Various embodiments of a dimmable power supply are disclosed herein. For example, some embodiments provide a dimmable power supply including an output driver, a variable pulse generator and a load current detector. The output driver has a power input, a control input and a load path. The variable pulse generator includes a control input and a pulse output, with the pulse output connected to the output driver control input. The variable pulse generator is adapted to vary a pulse width at the pulse output based on a signal at the control input. The load current detector has an input connected to the output driver load path and an output connected to the variable pulse generator control input. The load current detector has a time constant adapted to substantially filter out a change in a load current at a frequency of pulses at the variable pulse generator pulse output.
