... Precise constant-current control regulates accurate output current versus changes in input voltage and output voltage. The operating frequency is proportionally changed by the output voltage to guarantee DCM operation with higher efficiency and simple design. FLS3217 and FLS3247 provide protection features such as open-LED, protection. The current-limit level is automatically ~ 308V ...

... Functional Description FLS3217 / FLS3247 is an AC-DC PWM controller for LED lighting applications. TRUECURRENT regulate accurate LED current independent of input voltage, output voltage, and magnetizing inductance variations. The linear frequency control in the oscillator reduces conduction loss and maintains DCM operation in the wide range of output voltage, which implements high power factor correction in a single-stage flyback topology ...

... BCM Control The end of secondary diode conduction time is possibly over a switching period set by linear frequency control. In this case, FLS3217 and FLS3247 don’t allow CCM and the operation mode changes from DCM to BCM. Therefore, FLS3217 and FLS3247 eliminate sub- harmonic distortion in CCM. ...
