Overview

High-Side Sensing Constant Current Buck Controller for High Switching Frequency LED Driver FL7760 The FL7760 is a constant current step−down CCM controller for wide output power LED lighting applications.
The FL7760 adapts hysteretic reference architecture that accurately regulates LED current by sensing voltage across an external high side sense resistor.
This control scheme can stabilize LED current against input voltage and output load transient condition and implement optimal PWM and analog dimming control.
Time delay control method widens analog dimming range down to less than 5%.
FL7760 has low 200 mV reference voltage to maximize system efficiency and high frequency driving capability...
