MC33064D-5R2

Supervisors Overview

The MC33064D-5R2 is a high-voltage, single-channel power factor correction (PFC) controller manufactured by onsemi. It integrates a fixed-frequency current-mode PWM controller with an average current mode control scheme to achieve high efficiency and low harmonic distortion. The device operates from a wide supply voltage range and includes features such as brown-out protection, soft-start, and cycle-by-cycle current limiting. Designed for universal AC input applications, it supports continuous conduction mode (CCM) boost converters.

Supervisors Feature Summary

• Integrates average current mode control for improved power factor performance
• Includes built-in brown-out detection and programmable soft-start functionality
• Features cycle-by-cycle peak current limiting for robust operation

Supervisors Applications

• Universal AC-DC power supplies
• Computer and peripheral power supplies
• Battery chargers
• LED lighting drivers

Supervisors Procurement Notes

Verify the specific suffix 'R2' indicates tape and reel packaging when ordering. Confirm that the D package corresponds to the SOIC-16 footprint required for your PCB layout. Ensure compatibility with your target switching frequency and inductor design before finalizing procurement.

Supervisors Selection Notes

Select this component for designs requiring high power factor correction in single-phase applications. Consider the operating temperature range and thermal dissipation capabilities of the SOIC-16 package. Evaluate the need for external components like the compensation network and sense resistors to meet specific system requirements.

Supervisors Part Context

This part belongs to the MC3306x family of PFC controllers. It is designed to replace older discrete solutions or less integrated controllers. The D-16 package offers a balance of thermal performance and board space efficiency compared to larger packages.

Supervisors Replacement Considerations

Check for direct pin-to-pin compatible alternatives within the same manufacturer's portfolio. Verify that any substitute maintains the same voltage ratings and control loop characteristics. Ensure the replacement supports the required input voltage range and output power levels.
