MC33368PG

Overview

The MC33368PG is a Power Factor Correction (PFC) controller from onsemi's GreenLine series, designed for critical conduction mode (CRM) operation. It utilizes a 16-pin PDIP package with a 0.300-inch (7.62mm) width. The device operates within a supply voltage range of 10V to 16V and features a startup current of 16 mA. It supports an extended operating temperature range from -25°C to +125°C. This component is classified as obsolete and has been discontinued by the manufacturer.

Feature Summary

• Implements critical conduction mode (CRM) control for power factor correction applications.
• Designed for through-hole mounting in a standard 16-pin DIP configuration.
• Operates reliably across an extended industrial temperature range up to 125°C.

Applications

• Offline power supplies requiring power factor correction
• Consumer electronics AC-DC adapters
• Industrial power management systems

Procurement Notes

This component is officially listed as obsolete and discontinued by onsemi. Procurement should focus on verifying stock availability from authorized distributors or secondary market suppliers. Due to its end-of-life status, long-term supply stability cannot be guaranteed. Designers must evaluate alternative components for new production runs to ensure future manufacturability and support.

Selection Notes

Select this part only for maintenance or legacy system repairs where the original design specifies the MC33368PG. For new designs, consider modern replacements within the GreenLine family that offer active status and updated packaging options. Verify that the through-hole PDIP footprint matches the existing PCB layout constraints before proceeding with selection.

Part Context

The MC33368PG belongs to the GreenLine series of PFC controllers, which are optimized for high efficiency in offline applications. It serves as the through-hole variant of the MC33368 family, complementing surface-mount versions like the DR2G. The series focuses on simplifying design while maintaining compliance with energy efficiency standards.
