Description: High-Side Sensing Constant Current Buck Controller

Features

* Wide Input Range (8 VDC~70 VDC)
* Continuous Conduction Mode Operation
* Hysteretic LED Current Control
* Wide analog dimming range down to 5%
* Wide PWM dimming duty range to 0.2% at 2 kHz PWM freq.
* High switching frequency up to 1 MHz
* H

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 dimm
