ML4804 Power Factor Correction and PWM Controller Combo

The ML4804 is a controller for power factor corrected, switched mode power supplies. Power Factor Correction (PFC) allows the use of smaller, lower cost bulk capacitors, reduces power line loading and stress on the switching FETs, and results in a power supply that fully complies with IEC1000-3-2 sp.

ML4804 Features

* I Internally synchronized leading-edge modulated PFC and trailing-edge modulated PWM in one IC TriFault DetectTM for UL1950 compliance and enhanced safety VCCOVP provides additonal PFC fault protection Slew rate enhanced transconductance error amplifier for ultra-fast PFC response Low power: 200µA
