MC33260PG

Overview

The MC33260PG is a GreenLine compact power factor controller from onsemi, designed for critical conduction mode (CrM) PFC applications. It operates within a supply voltage range of 7V to 36V and supports an operating temperature range from -40°C to 105°C. The device features zero-power detection and utilizes a PDIP-8 package with through-hole mounting. Key electrical parameters include a start-up supply current of 0.25mA, a maximum source current of 10μA, and a maximum reverse current of 500,000μA. The component dimensions are 10.16mm in length and 3.44mm in height.

Feature Summary

• Implements critical conduction mode control for efficient power factor correction
• Integrates zero-power detection capability to minimize standby losses
• Designed as a compact solution for cost-sensitive power supplies

Applications

Procurement Notes

Verify the specific suffix PG confirms the PDIP-8 tube packaging configuration. Confirm that the component status aligns with project lifecycle requirements, as some sources indicate this part may be obsolete or have limited availability. Ensure the manufacturer is identified as onsemi or its predecessor ON Semiconductor for compatibility checks.

Selection Notes

Select this component for applications requiring a dedicated CrM PFC controller with integrated zero-power detection. The wide input voltage range and robust operating temperature specifications make it suitable for various industrial and consumer environments. Consider the through-hole package constraint when designing PCB layouts compared to surface-mount alternatives.

Part Context

The MC33260 belongs to the GreenLine family of power controllers, which focus on providing high-performance solutions with minimal external component counts. This series targets applications where size, cost, and efficiency are critical design drivers. The PG suffix specifically denotes the plastic dual in-line package variant.
