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, VDD 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).
