ML4827CP2

Overview

The ML4827CP2 is a power factor correction controller designed for switched mode power supplies. It operates in discontinuous conduction mode with an internal oscillator frequency of 80kHz. The device is housed in a 16-pin DIP package (0.300 inch / 7.62mm) and supports through-hole mounting. It functions within a supply voltage range of 0V to 7V and maintains an operating temperature range of 0°C to 70°C.

Feature Summary

• Integrated circuitry for safety compliance in power factor corrected designs
• Supports discontinuous transition mode operation
• Includes internal oscillator for fixed frequency control

Applications

• Power factor corrected switched mode power supplies
• AC-DC conversion systems requiring safety compliance
• Discontinuous conduction mode PFC controllers

Procurement Notes

Verify the specific suffix 'CP2' against the manufacturer's official datasheet to confirm pinout, package dimensions, and electrical characteristics match your design requirements. Ensure the component meets RoHS compliance standards if required by your assembly process. Cross-reference the Fairchild Semiconductor part number with current onsemi documentation, as corporate ownership may affect datasheet availability.

Selection Notes

Select this component for applications requiring a dedicated PFC controller in discontinuous mode. The 16-DIP package facilitates prototyping and through-hole assembly. Confirm that the 80kHz switching frequency aligns with your electromagnetic interference constraints and transformer design. Verify input voltage ranges and thermal management capabilities for the 0°C to 70°C operating environment.

Part Context

The ML4827 series belongs to Fairchild Semiconductor's portfolio of power management integrated circuits. This specific model is engineered for AC-DC power supplies where power factor correction is mandated by regulatory standards. The CP2 designation indicates a commercial grade temperature range and standard plastic DIP packaging suitable for general industrial and consumer electronics applications.

Replacement Considerations

Consult official substitution guides from onsemi or Fairchild Semiconductor for direct replacements. Generic equivalents may differ in oscillator accuracy, protection features, or pin compatibility. Verify that any substitute IC supports the same discontinuous conduction mode architecture and 16-pin DIP footprint.
