MC34262P

MC34262P Description

The MC34262P, manufactured by onsemi, is a Power Factor Correction (PFC) controller designed for critical conduction mode (CRM) applications. This through-hole mounted, 8-DIP packaged IC operates within a wide supply voltage range of 12V to 28V and is suitable for operating temperatures between 0°C and 85°C. The MC34262P is classified under the EAR99 Export Control Classification Number (ECCN) and has a moisture sensitivity level (MSL) of 1, indicating unlimited storage time before baking is required. Although the product status is marked as obsolete, it remains a popular choice for its unique features and performance benefits.

MC34262P Features

• Wide Operating Voltage Range: The MC34262P can operate with a supply voltage between 12V and 28V, making it suitable for a variety of applications and power sources.
• Critical Conduction Mode (CRM) Operation: This mode allows for high efficiency and low total harmonic distortion (THD), which is crucial for meeting stringent power quality standards.
• Low Startup Current: The MC34262P consumes only 250 µA during startup, which is beneficial for applications where power consumption needs to be minimized.
• REACH Unaffected Status: This indicates that the product does not contain any substances of very high concern (SVHC) as per the Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) regulation.
• Through-Hole Mounting: The 8-DIP package allows for easy integration into existing through-hole printed circuit board (PCB) designs.

MC34262P Applications

The MC34262P is ideal for applications where high efficiency and power quality are paramount. Some specific use cases include:

• Switching Power Supplies (SPS): Especially in high-power applications where high efficiency and low THD are required.
• Uninterruptible Power Supplies (UPS): For maintaining high power quality and efficiency during backup power operations.
• Battery Chargers: To ensure efficient and safe charging of batteries with minimal power loss and electromagnetic interference.
• Industrial Automation Equipment: For controlling power quality in motor drives and other high-power industrial applications.

Conclusion of MC34262P

While the MC34262P is classified as obsolete, its robust performance, wide operating voltage range, and low startup current make it a reliable choice for applications demanding high efficiency and power quality. Its through-hole mounting and REACH unaffected status also add to its appeal in legacy systems and where compliance with environmental regulations is a priority. Despite its obsolescence, the MC34262P continues to offer a competitive edge in certain applications where its unique features align with specific project requirements.
