NCP1618CDR2G

Overview

The NCP1618CDR2G is a Power Factor Correction (PFC) controller from onsemi, designed for multi-mode operation including continuous conduction mode (CCM), discontinuous conduction mode (DCM), and transition mode. It operates within a supply voltage range of 9.6V to 35V and supports switching frequencies up to 130kHz. The device features a 10-pin SOIC package and functions reliably across an extended temperature range from -40°C to +125°C. Key electrical parameters include a startup current of 4mA, a maximum source current of 500mA, and a maximum reverse current of 800mA. It complies with RoHS standards.

Feature Summary

• Supports multi-mode PFC operation for optimized efficiency across varying load conditions
• Integrated metal tweak functionality for enhanced performance tuning
• Capable of high-frequency switching up to 130kHz for compact design

Applications

• Power factor correction stages in AC-DC power supplies
• Universal input adapter designs
• Consumer electronics power management systems

Procurement Notes

Verify the specific suffix 'CDR2G' against official onsemi documentation to confirm package type and tape/reel specifications. Ensure compatibility with your PCB footprint for the 10-pin SOIC form factor. Cross-reference the datasheet for thermal requirements given the 125°C operating limit. Confirm that the component meets all necessary regulatory standards for your target market.

Selection Notes

Select this component when multi-mode PFC control is required for improved light-load efficiency. Consider the 130kHz frequency limit for magnetic component sizing. Evaluate the 35V maximum supply voltage against your circuit's operational peaks. The 10-pin SOIC package offers a balance between pin count and board space constraints.

Part Context

This part belongs to the NCP1618 series of PFC controllers. It is distinct from other onsemi models like the NCP1616 or NCP1608 by its specific multi-mode capabilities and metal tweak feature. The series targets high-efficiency power conversion applications requiring robust control algorithms.
