ML4841 Datasheet Variable Feedforward Pfc/pwm Controller Combo

Manufacturer: Fairchild (now onsemi)

Overview: www.fairchildsemi.com ML4841 Variable Feedforward PFC/PWM Controller.

General Description

The ML4841 is a controller for power factor corrected, switched mode power supplies.

Power Factor Correction (PFC) allows the use of smaller, lower cost bulk capacitors, reduces power line loading and stress on the switching FETs, and results in a power supply that fully complies with IEC1000-2-3 specifications.

The ML4841 includes circuits for the implementation of a leading edge, average current, “boost” type power factor correction, and a trailing edge, pulse width modulator (PWM).

Key Features

  • Internally synchronized PFC and PWM in one IC.
  • Low total harmonic distortion.
  • Reduces ripple current in the storage capacitor between the PFC and PWM sections.
  • Average current, continuous mode, boost type, leading edge PFC.
  • High efficiency trailing edge PWM can be configured for current mode or voltage mode operation.
  • Average line voltage compensation with brown-out control.
  • PFC overvoltage comparator eliminates output “runaway” due t.
