Description
The FL7734 is a highly integrated PWM controller with advanced Primary-Side-
Regulation (PSR) technique to minimize components for low power LED lighting
solutions. Using the innovative TRUECURRENT® technology for tight constant-
current control, it enables designs with constant-current (CC) tolerance of
less than ±1% in the wide line voltage range to meet stringent LED brightness
requirements.
FL7734 can operate with all types of phase cut dimmers. Phase cut dimming is
managed smoothly by Fairchild’s proprietary constant input current control and
bleeding current control to achieve excellent dimmer compatibility without
visible flicker.
The controller can automatically detect whether there is a dimmer connection.
In non dimming mode, the operating mode is set to optimize power factor and
THD by enabling linear frequency control and voltage mode based on DCM.
An external high-voltage bleeding circuit is utilized to implement fast
startup and high system efficiency. The FL7734 also provides powerful
protections, such as LED open / short, sensing resistor shorted, and over
temperature for high system reliability. The FL7734 is available in 16-pin
Small-Outline Package (SOP).
