ML4801IS

Overview

The ML4801IS is a Power Factor Correction (PFC) and PWM controller manufactured by onsemi. It integrates PFC and PWM control functions in a single package, designed for high-efficiency power conversion applications. The device operates with a switching frequency of 200 kHz and features a supply voltage range up to 18V. It includes an internal oscillator and supports average current mode control for the PFC stage. The component is housed in a 16-pin SOIC package and is rated for operation within a temperature range of -40°C to 85°C.

Feature Summary

Integrates both Power Factor Correction and Pulse Width Modulation controllers into a single IC
Supports average current mode control for improved PFC performance
Includes an internal oscillator for fixed-frequency switching operation
Designed for high-efficiency power conversion systems

Applications

Power factor correction stages in AC-DC converters
Combined PFC and PWM power supply designs
High-efficiency offline power supplies
Industrial power conversion equipment

Procurement Notes

Verify availability status as this component may be discontinued or subject to limited supply. Confirm exact ordering part number including suffixes if applicable. Check datasheet revisions for any functional changes. Ensure compatibility with existing design requirements before procurement.

Selection Notes

Select this component when integrated PFC and PWM control is required in a single package. Consider the 200 kHz switching frequency and 18V supply limit during design. Verify thermal management capabilities for the SOIC-16 package. Compare against standalone PFC controllers if separate optimization is needed.

Part Context

The ML4801IS belongs to onsemi's portfolio of power management integrated circuits. It is part of the ML48xx series of PFC controllers. The device utilizes onsemi's Treo platform technology for analog and mixed-signal integration. This series targets efficient power conversion solutions for various industrial and commercial applications.

Replacement Considerations

ML4801ISX is listed as a variant from MICREL, but cross-manufacturer substitution requires careful verification of pinouts and electrical characteristics. No direct equivalent from onsemi is explicitly confirmed in the provided data.
