ML4824CS1X

Overview

The ML4824CS1X is a discontinued Power Factor Correction (PFC) controller from onsemi, belonging to the ML4824 series. It operates in average current mode with a fixed switching frequency of 76 kHz. The device is housed in a 16-SOIC surface-mount package and supports a supply voltage range of 10.5V to 13.2V. Designed for industrial environments, it functions within a temperature range of -40°C to 85°C. Key electrical characteristics include a startup current of 700 µA. This component was manufactured as part of onsemi's standard product line for power management applications.

Feature Summary

• Implements average current mode control for PFC applications
• Features a fixed 76 kHz switching frequency
• Designed for surface-mount integration via 16-SOIC packaging

Applications

• Power factor correction circuits in AC-DC converters
• Industrial power supply systems
• General-purpose power management designs requiring average current mode control

Procurement Notes

Verify component status carefully before design finalization. The ML4824CS1X is officially listed as discontinued by the manufacturer. Sourcing new units may be restricted or limited to existing stock. Engineers should confirm availability through authorized distributors and evaluate long-term supply chain stability. Alternative solutions or lifecycle management strategies are recommended due to the end-of-life status.

Selection Notes

Select this component only if legacy compatibility or specific historical design requirements necessitate the ML4824 series. Given its discontinued status, newer alternatives offering similar average current mode PFC functionality should be evaluated for new designs. Consider package constraints, operating temperature ranges, and switching frequency requirements when comparing against active replacement options.

Part Context

The ML4824CS1X is a variant of the ML4824 family, which includes DIP and SOIC packages. It falls under onsemi's power management category, specifically PFC controllers. The 'CS1X' suffix denotes the 16-SOIC package type. This part represents an older generation of PFC technology compared to modern integrated solutions.

Replacement Considerations

As the ML4824CS1X is discontinued, direct substitutes must be identified based on functional equivalence. Review onsemi's current PFC portfolio for active components with comparable average current mode control and 76 kHz operation. Ensure pinout compatibility and thermal performance match the original design specifications.
