Abstract
Described herein is a device comprising circuitry configured to determine, based on an input signal level, one of a first mode of operation and a second mode of operation for a light-emitting-diode (LED) driver. The circuitry activates a loop-filter associated with the first mode of operation of the LED driver in response to the input signal level being below a predetermined threshold. Moreover, the circuitry activates a pulse modulator associated with the second mode of operation of the LED driver in response to the input signal level being above the predetermined threshold.
