Product Summary

The ML4800CP is a power factor correction and PWM controller. It includes a TriFault Detect function to help ensure that no unsafe conditions will result from single component failure in the PFC. Gate-drivers with 1A capabilities minimize the need for external driver circuits. Low power requirements improve efficiency and reduce component costs. An over-voltage comparator shuts down the PFC section in the event of a sudden decrease in load. The PFC section also includes peak current limiting and input voltage brownout protection.

Parametrics

ML4800CP absolute maximum ratings: (1)VCC: 18V; (2)Voltage on any other pin: VCCZ+0.3V; (3)Peak PFC out current: 1A; (4)PFC out: 1.5μJ; (5)junction temperature: 150℃; (6)storage temperature range: -65 to 150℃; (7)lead temperature: 260℃.

Features

ML4800CP features: (1)Internally synchronized leading-edge PFC and trailingedge PWM in one IC; (2)TriFault Detect for UL1950 compliance and enhanced safety; (3)Slew rate enhanced transconductance error amplifier for ultra-fast PFC response; (4)Low power: 200µA startup current, 5.5mA operating current; (5)Low total harmonic distortion, high PF; (6)Reduced ripple current in storage capacitor between PFC and PWM sections; (7)Average current, continuous boost leading edge PFC; (8)PWM configurable for current-mode or voltage mode operation; (9)Current fed gain modulator for improved noise immunity.
