MC33262DG

Overview

The MC33262DG is a Power Factor Correction (PFC) controller from the MC332 series, manufactured by onsemi. It is designed for critical conduction mode (CRM) applications and features an integrated high-voltage startup circuit. The device supports a supply voltage range of 12V to 25V and operates within a temperature range of -20°C to +85°C. Packaged in an 8-SOIC surface-mount format with a width of 3.90mm, it includes a 50µA start-up current specification.

Feature Summary

• Integrated high-voltage startup circuit eliminates external bias components
• Supports critical conduction mode (CRM) operation for efficient power factor correction
• Compact 8-SOIC surface-mount package design

Applications

• Power factor correction in AC-DC converters
• Critical conduction mode PFC stages
• General-purpose power supply designs requiring CRM control

Procurement Notes

Verify component authenticity through authorized channels. Confirm that the specific suffix 'DG' corresponds to the SOIC package variant. Check for obsolescence status or lifecycle notices prior to finalizing procurement plans to ensure long-term availability.

Selection Notes

Select this component for CRM-based PFC designs requiring integrated startup functionality. Ensure the operating environment stays within the specified -20°C to +85°C range. Validate compatibility with the required 12V to 25V supply voltage constraints during system architecture planning.

Part Context

This part belongs to the MC332 series of PFC controllers. It serves as a specialized solution for power factor correction applications, distinct from general-purpose operational amplifiers or regulators found in other onsemi product lines. The series focuses on efficient power management using CRM techniques.

Replacement Considerations

Public confirmed substitute part numbers include L6562D from STMicroelectronics.
