Description
The highly integrated FAN6921ML combines a Power
Factor Correction (PFC) controller and a Quasi-
Resonant PWM controller. Integration provides cost-
effect design and allows for fewer external components.
For PFC, FAN6921ML uses a controlled on-time
technique to provide a regulated DC output voltage and
to perform natural power factor correction. With an
innovative THD optimizer, FAN6921ML can reduce
input current distortion at zero-crossing duration to
improve THD performance.
For PWM, FAN6921ML enhances the power system
performance through valley detection, green-mode
operation, and high / low line over power compensation.
FAN6921ML provides: secondary-side open-loop and
over-current protection, external latch triggering,
adjustable over-temperature protection by RT pin and
external NTC resistor, internal over-temperature
shutdown, V
DD
pin OVP, and DET pin over-voltage for
output OVP, and brownin/out for AC input voltage
under-voltage protection (UVP).
The FAN6921ML controller is available in a 16-pin small
outline package (SOP).
