FAN6921ML

Integrated Critical Mode PFC/Quasi-Resonant

Current Mode PWM Controller

Features

Description

The highly integrated FAN6921ML combines a Power

Factor Correction (PFC) controller and Quasi-

Resonant PWM controller. Integration provides cost-

effect design and allows for fewer external components.

Integrated PFC and Flyback Controller

Critical Mode PFC Controller

Zero-Current Detection for PFC Stage

Quasi-Resonant Operation for PWM Stage

Internal Minimum t_off8µs for QR PWM Stage

Internal 10ms Soft-Start for PWM

Brownout Protection

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.

H/L Line Over-Power Compensation (OPC)

Latched Protection (FB Pin)

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_DDpin OVP, and DET pin over-voltage for

output OVP, and brownin/out for AC input voltage

under-voltage protection (UVP).
