ML4841
Variable Feedforward PFC/PWM Controller Combo
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 over
voltage comparator eliminates output “runaway” due to load removal • Current fed multiplier for improved noise immunity • Over
voltage protection, UVLO, and soft start
