ML4841CP

Overview

The ML4841CP is a Power Factor Correction (PFC) controller manufactured by onsemi. It integrates average current mode control with a PWM controller for power factor correction applications. The device operates at a switching frequency of 200kHz and supports a supply voltage range of 0V to 7V. It is designed for through-hole mounting in PDIP-16 packages and functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• Integrates average current mode PFC control with PWM functionality
• Supports fixed 200kHz switching frequency operation
• Designed for low-voltage supply environments up to 7V

Applications

• Power factor correction circuits
• AC-DC power supplies
• Industrial power conversion systems

Procurement Notes

Verify component authenticity as the ML4841CP is listed as obsolete by major distributors. Confirm package integrity and pin compatibility before integration into new designs, considering potential availability constraints from secondary market sources.

Selection Notes

Select this component for legacy designs requiring integrated PFC and PWM control in a PDIP-16 package. Ensure system requirements align with the 200kHz frequency limit and 0-7V supply constraint. Evaluate thermal performance within the specified 0°C to 70°C operating range for target applications.

Part Context

The ML4841CP belongs to onsemi's portfolio of power management integrated circuits. It serves as a specialized solution for improving efficiency in AC-DC conversion stages. As an obsolete part, it remains relevant for maintenance and repair scenarios in existing industrial equipment.

Replacement Considerations

Consult official onsemi documentation for direct or pin-compatible replacements. Verify electrical specifications and package dimensions match when substituting due to the component's obsolete status.
