Fairchild ML4824CS1

平均电流76kHz

Overview

• 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 boost leading edge PFC• Fast transconductance error amp for voltage loop• High efficiency trailing edge PWM can be configured for current mode or voltage mode operation• Average line voltage compensation with brownout control• PFC overvoltage comparator eliminates output “runaway” due to load removal• Current fed gain modulator for improved noise immunity• Overvoltage protection, UVLO, and soft start
