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.
The FL77905 provides phase-cut dimming with wide
dimming range, smooth dimming control and good
dimmer compatibility. It achieves high efficiency with
high PF and low THD which makes the FL77905
suitable for high-efficiency LED lighting systems. The
FL77905 can also be used with a rheostat dimmer
switches which are suitable for desktop or indoor lamps.
The FL77905 has a dedicated DIM pin which is
designed to be used with analog or digital PWM
dimming.
Operation of FL77905 admits driving higher-wattage
systems, such as street lights and down lights, by
simply parallel connecting the driver ICs.
