ML4821CS Description

Short technical summary and product information.

The ML4821CS from ON Semiconductor is a versatile Power Factor Correction (PFC) controller IC. It is engineered to provide complete control for boost-type power factor correction systems using an average current sensing method. This design enhances system noise immunity and offers features like average line compensation with brown-out control and a precision buffered 5V reference.

 

The ML4821CS operates with a voltage range of 12V to 18V and a frequency of 1MHz, drawing a current of 600 µA. It includes a 1A peak current totem-pole output drive and an overvoltage comparator to prevent output runaway. The operating temperature range is from 0°C to 70°C.

 

This IC is housed in a 20-SOIC package and is designed for surface mount applications. Its internal circuitry includes a gain modulator, error amplifiers, and an oscillator with a shutdown input for sleep mode functionality. The output driver is internally limited to 17V, and a shutdown mode is activated below 0.7V at the OVP pin.
