供应功率因数校正和PWM组合控制器ML4824IP1

ML4824(功率因数校正和PWM组合控制器)
Power Factor Correction and 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 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
