ML4800 Power Factor Correction and PWM Controller Combo

The ML4800 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.

ML4800 Features

* I Internally synchronized leading-edge PFC and trailingedge PWM in one IC TriFault Detect™ for UL1950 compliance and enhanced safety Slew rate enhanced transconductance error amplifier for ultra-fast PFC response Low power: 200µA startup current, 5.5mA operating current Low total harmonic distortio
