ML4804 Datasheet (Micro Linear) - Power Factor Correction and PWM Controller Combo

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
