FAN4800 Datasheet - Fairchild Semiconductor

FAN4800 Low Start-Up Current PFC/PWM Controller Combos

The FAN4800 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 IEC-1000-3-2 .

FAN4800 Features

* Low Startup Current (100µA Typical)

* Low Operating Current (2.5mA Typical)

* Low Total Harmonic Distortion, High Power Factor

* Pin-Compatible Upgrade for the ML4800

* Average Current, Continuous or Discontinuous Boost, Leading-Edge PFC

* Slew Rate
