NCP1606ADR2G

Overview

The NCP1606ADR2G is a Power Factor Correction (PFC) controller manufactured by onsemi, designed for critical conduction mode (CRM) applications. It operates within a supply voltage range of 10.3V to 20V and features a low startup current of 20 µA. The device is housed in an 8-SOIC package with a maximum power dissipation of 800 mW. It supports an operating temperature range from -40°C to +125°C and complies with RoHS standards.

Feature Summary

• Supports critical conduction mode (CRM) operation for efficient power factor correction.
• Low startup current consumption of 20 µA to minimize standby power loss.
• Integrated thermal protection and robust design for high-temperature environments.

Applications

• Power supplies for LED lighting systems
• AC-DC adapters for consumer electronics
• General purpose power factor correction circuits

Procurement Notes

Verify the component status as Not Recommended for New Design (NRND) before finalizing any procurement plans. Confirm that the specific ordering suffix matches the required package and tape/reel specifications. Ensure compliance with RoHS directives and check for any recent Product Change Notifications (PCN) regarding manufacturing site or material updates prior to placing orders.

Selection Notes

Select this component for designs requiring CRM PFC control with low quiescent current. The 8-SOIC package suits surface-mount assembly processes. Consider the NRND status when planning long-term production runs. Evaluate the 800 mW power dissipation limit against the expected thermal environment to ensure reliable operation within the specified temperature range.

Part Context

This part belongs to the NCP1606 series of PFC controllers from onsemi. It is categorized under PMIC - Power Management ICs. The device is specifically engineered for single-stage PFC solutions, offering a compact footprint and simplified external component count compared to traditional multi-stage approaches.

Replacement Considerations

The NCP1607BDR2G is listed as a direct replacement option by the manufacturer. Verify functional compatibility and pinout alignment before substitution. Note that both parts share the NRND status, so availability may be limited for new projects.
