ML4824IP1

Overview

The ML4824IP1 is a Power Factor Correction (PFC) and Pulse Width Modulation (PWM) controller combo integrated circuit manufactured by onsemi. It operates in a 16-pin DIP package with an average current control mode for the PFC section and configurable trailing-edge PWM for high efficiency. The device supports a switching frequency of 76 kHz and functions within a supply voltage range of 10.5V to 13.2V. It is designed for through-hole mounting and operates at temperatures from -40°C to 85°C, featuring internally synchronized PFC and PWM sections to reduce ripple current.

Feature Summary

• Combines internally synchronized PFC and PWM controllers in a single IC
• Utilizes average current continuous boost leading edge PFC control
• Configurable high-efficiency trailing edge PWM operation
• Designed to reduce ripple current between PFC and PWM sections

Applications

• Power factor correction systems
• Average current mode power supplies
• High efficiency trailing edge PWM applications

Procurement Notes

Verify component authenticity and datasheet alignment before integration. Confirm package type and pinout compatibility with existing designs. Check for obsolescence status as this specific part number may be discontinued or subject to lifecycle changes. Ensure environmental compliance documentation matches project requirements.

Selection Notes

Select this component for designs requiring combined PFC and PWM functionality in a single package. Consider the 16-pin DIP package for through-hole assembly needs. Evaluate the 76 kHz switching frequency against system thermal and EMI constraints. Verify that the average current control mode meets the specific power factor and harmonic distortion requirements of the target application.

Part Context

The ML4824 series represents onsemi's solution for integrated power factor correction and pulse width modulation control. This specific IP1 variant denotes the 16-pin DIP package configuration. It belongs to a family of controllers designed to simplify power supply design by integrating multiple control loops into one device, reducing component count and board space.

Replacement Considerations

Check for direct substitutes within the ML4824 series such as ML4824CP2_Q for different temperature ranges or packaging. Verify functional equivalence if considering cross-manufacturer alternatives. Ensure any replacement maintains the same switching frequency and control architecture.
