ML4800CS

Overview

The ML4800CSX is a Power Factor Correction (PFC) and Pulse Width Modulation (PWM) controller combo manufactured by Fairchild Semiconductor. It operates in a voltage-mode control technique with a maximum input voltage of 16.5 V, a minimum input voltage of 10.8 V, and a nominal input voltage of 15 V. The device is housed in a 16-pin SOIC package measuring 9.9 mm in length.

Feature Summary

• Integrates PFC and PWM controllers for switched mode power supplies
• Supports average current mode operation
• Includes post regulator functionality

Applications

• Power factor corrected switched mode power supplies

Procurement Notes

Verify the manufacturer designation as Fairchild Semiconductor or its successor onsemi during procurement. Confirm the specific suffix 'CSX' matches the required 16-pin SOP package and lead-free RoHS compliance status. Ensure the component meets the specified voltage parameters before integration into designs requiring 10.8 V to 16.5 V input ranges.

Selection Notes

Select this component for applications requiring a combined PFC and PWM solution in a compact 16-lead narrow body package. It is suitable for designs needing voltage-mode control with an integrated post regulator. Verify compatibility with the required operating temperature range and ensure the system design accommodates the specific input voltage thresholds defined in the datasheet.

Part Context

This part belongs to the ML4800 series of power management ICs designed for high-efficiency power conversion. It represents an evolution in PFC technology, offering a compact solution for meeting regulatory standards such as IEC1000-3-2. The device simplifies board layout by combining critical control functions into a single BiCMOS integrated circuit.

Replacement Considerations

The FAN4800CSMY from onsemi serves as a direct replacement within the same product family. When substituting, verify that the pinout and electrical characteristics remain compatible with the existing design requirements.
