ML4822CS

Overview

The ML4822CS is a Power Factor Correction (PFC) controller manufactured by Fairchild Semiconductor. It integrates average current mode control with pulse width modulation for high-efficiency power conversion. The device operates within a supply voltage range of 10.5V to 13.2V and features a switching frequency of 76kHz. It is housed in a 16-pin SOIC package with an operating temperature range of 0°C to 70°C. The startup current is specified at 700 µA, ensuring reliable initialization during power-up sequences.

Feature Summary

Integrates average current mode control for precise power factor correction
Combines PFC controller functionality with post-regulator capabilities
Supports configurable operation modes including current mode configuration

Applications

Power factor correction circuits in AC-DC converters
High-efficiency power supply designs requiring active PFC
Industrial power management systems

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and lead times prior to ordering. Check for obsolete status as some variants may be discontinued. Ensure packaging specifications match design requirements. Validate datasheet revisions against current production versions.

Selection Notes

Evaluate thermal performance within the specified 0°C to 70°C operating range. Consider the 76kHz switching frequency for electromagnetic interference filtering requirements. Assess compatibility with downstream post-regulator stages. Verify input voltage stability within the 10.5V to 13.2V operational window. Review pinout compatibility with existing PCB layouts for the 16-SOIC package.

Part Context

This component belongs to the ML4824 family of PFC controllers, originally developed by Fairchild Semiconductor and later acquired by onsemi. The ML4822 series provides integrated solutions for power factor correction, combining voltage-mode and current-mode control techniques. These devices are designed for applications requiring high efficiency and low harmonic distortion in power conversion systems.
