The ML4821CP from On Semiconductor is an integrated circuit designed to provide complete control for boost-type power factor correction (PFC) systems using average current sensing. This method helps achieve the lowest possible harmonic distortion.
The IC features average line compensation with brown-out control, a precision buffered 5V reference, and a 1A peak current totem-pole output drive. It includes an overvoltage comparator to prevent output runaway and a sleep mode shutdown input. The operating voltage range is 12V to 18V, with an operating current of 600 µA and a frequency of 1MHz.
Designed for enhanced system noise immunity, the ML4821CP incorporates a gain modulator, average current error amplifier, output error amplifier, over-voltage protection comparator, and shutdown logic. Start-up is simplified by an under-voltage lockout circuit. The operating temperature range is 0°C to 70°C.
This component is supplied in an 18-DIP (0.300", 7.62mm) package and is designed for Through Hole mounting.
