NCP1618ADR2G

Overview

The NCP1618ADR2G is a high-voltage power factor correction controller from the onsemi NCP1618 series. It operates with a switching frequency of 130 kHz and supports continuous conduction mode (CCM). The device functions within a supply voltage range of 9.5V to 35V and withstands operating temperatures from -40°C to +125°C. It utilizes a 9-lead SOIC package for surface mount installation.

Feature Summary

• Supports continuous conduction mode operation for power factor correction applications
• Integrated high-voltage startup circuitry for simplified design

Applications

• Power factor correction in AC-DC power supplies
• Universal input power adapters
• Consumer electronics power stages

Procurement Notes

Verify the specific suffix 'ADR' against official datasheets to confirm pinout and electrical characteristics, as variations exist within the NCP1618 family. Ensure compatibility with the target PCB footprint, specifically the 9-SOIC package dimensions. Cross-reference RoHS compliance status with current manufacturer declarations before finalizing procurement.

Selection Notes

Select this component for designs requiring a 130 kHz switching frequency and CCM operation. The wide supply voltage range accommodates various input conditions. Verify that the thermal requirements align with the specified junction temperature limits for the intended enclosure environment.

Part Context
