March 2001 PRELIMINARY ML4804 Power Factor Correction and PWM Controller Combo GENERAL DESCRIPTION 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 specification.
Intended as a BiCMOS enhancement of the industry-standard ML4824, the ML4804 includes circuits for the implementation of leading edge, average current, “boost” type power factor correction and a trailing edge, pulse width modulator (PWM).
It also includes a TriFault Detect™ function to ...
