Description

The highly integrated FAN6921AMR 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, FAN6921AMR uses a controlled on-time

technique to provide a regulated DC output voltage and

to perform natural power factor correction. An innovative

THD optimizer reduces input current distortion at zero-

crossing duration to improve THD performance.

For PWM, FAN6921AMR provides several functions to

enhance power system performance: valley detection,

green-mode operation, high / low line over-power

compensation. Protection functions include secondary-

side open-loop and over-current with auto-recovery

protection, external latch triggering, adjustable over-

temperature protection by the RT pin and external NTC

resistor, internal over-temperature shutdown, VDD pin

OVP, DET pin over-voltage for output OVP, and brown-

in / out for AC input voltage UVP.

The FAN6921AMR controller is available in a 16-pin,

small-outline package (SOP).
