FL77905 Product details

Description

The FL77905 is a direct AC line LED driver with minimal number of external RC passive components.

In normal configuration, one resistor is to adjust LED power, and one capacitor is to provide a stable voltage to an internal biasing shunt regulator.

Features

The simplest Direct AC LED Driver with Only Two External RC Passive Components.
Wide AC Input Range : 90~305 VAC.
Three Integrated High-Voltage LED Constant Current Sinks of up to 75 mA (RMS) Capability.
TRIAC Dimmable (Leading/Trailing Edge).
Rheostat Dimmable.
Analog/Digital PWM Dimming Function.
High Power Factor (above 0.98 in normal configuration).
Adjustable LED Power with an External Current Sense Resistor.
Low Harmonic Content (THD under 20%.
