ML4803 Datasheet (Micro Linear) - 8-Pin PFC and PWM Controller Combo

ML4803, 8-Pin PFC and PWM Controller Combo

The ML4803 is a space-saving controller for power factor corrected, switched mode power supplies that offers very low start-up and operating currents.

Power Factor Correction (PFC) offers the use of smaller, lower cost bulk capacitors, reduces power line loading and stress on the switching FETs, and
