Claim:
1. A light emitting diode (LED) driver system comprising: a control signal input configured to receive a control signal; a pulse-width modulation (PWM) input configured to receive a PWM signal; a driver having a first input coupled to the PWM input, a second input coupled to the control signal input, a third input configured to receive an LED current sense signal, a fourth input configured to receive a first feedback signal, and a differential output, wherein the driver is configured to deliver a level of current indicated by the control signal, to a light emitting diode (LED) load when the PWM signal is ON and stop delivering the level of current when the PWM signal is OFF; an output capacitance element coupled across the differential output of the driver; and a first feedback path coupled between the differential output of the driver and the fourth input of the driver, wherein the first feedback path has a store circuit configured to:
