The ML4805 is a controller for power factor corrected, switched mode power supplies.

of this combined PFC and PWM controller are low start-up and operating currents. 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 IEC1000-2-3 specifications. The ML4805 includes circuits for the implementation of a leading edge, average current “boost” type power factor correction and a trailing edge pulse width modulator. The PFC frequency of th.
