About this product
The ML4800CP is a controller IC for power-factor-corrected switch-mode power supplies. It combines an average-current boost PFC stage with a trailing-edge PWM output, and is described as a BiCMOS version of the ML4824. It includes TriFault Detect protection to help prevent unsafe operating conditions in AC-input power supplies.

Frequently asked questions
Can it replace the ML4824 directly?
The listing describes it as a BiCMOS version of the ML4824, but check the datasheet for pinout and electrical differences before using it as a substitute.
Is this a complete power supply?
No. It is a controller IC. A working PFC power stage also needs external power MOSFETs, a boost inductor, sensing components and the rest of the supply circuitry.
