NCP1927DR2G

Overview

The NCP1927DR2G is a combination power factor correction (PFC) and flyback controller manufactured by onsemi. It integrates primary-side control blocks for both PFC and flyback topologies into a single IC, designed specifically for applications such as flat panel displays. The device supports synchronous rectification and operates within a wide input voltage range to ensure efficient power conversion in compact form factors.

Feature Summary

• Integrates primary-side control blocks for power factor correction and flyback controllers
• Designed for high-efficiency power conversion in space-constrained applications
• Supports synchronous rectification for improved performance

Applications

• Flat panel display power supplies
• Integrated AC-DC converter designs
• High-density power adapters

Procurement Notes

Verify the specific suffix DR2G against the official datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with your PCB footprint and reflow profile requirements. Cross-reference the manufacturer's latest revision history for any design changes or obsolescence notices before finalizing procurement.

Selection Notes

Select this component when a single-chip solution for combined PFC and flyback control is required to reduce bill of materials and board space. It is suitable for designs prioritizing integration over discrete component flexibility. Evaluate thermal management needs based on the SOIC-8 package limitations and expected load conditions.

Part Context

This part belongs to onsemi's portfolio of power management integrated circuits, specifically targeting AC-DC conversion applications. It falls under the category of combination controllers, distinguishing itself from standalone PFC or flyback chips by offering dual functionality in one package.

Replacement Considerations

Check for direct pin-to-pin replacements within the NCP1927 family or updated revisions. Verify if alternative combination controllers from other manufacturers meet the same electrical specifications and packaging constraints.
