ML4841 - Variable Feedforward PFC/PWM Controller Combo

General Description

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

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.
