NCP1601ADR2G

Overview

The NCP1601ADR2G is a power factor correction controller manufactured by onsemi, designed for critical conduction mode (CRM) and transition mode applications. It operates within a supply voltage range of 9.6V to 18V and supports switching frequencies up to 58kHz. The device features a low startup current of 17µA and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in an 8-SOIC surface-mount format with a width of 3.90mm, it belongs to the NCP1601 series under PMIC classification.

Feature Summary

• Supports Critical Conduction Mode (CRM) and Transition Mode operation for efficient power factor correction
• Low startup current specification reduces standby power consumption during initial activation
• Extended thermal operating range ensures reliability in demanding environmental conditions

Applications

• Power factor correction circuits requiring CRM control
• Transition mode PFC designs for medium power applications
• General purpose AC-DC converter front ends

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as required by project specifications. Check for obsolescence notices or lifecycle changes prior to final procurement decisions. Ensure packaging integrity matches specified tape and reel requirements for automated assembly processes.

Selection Notes

Evaluate suitability based on required switching frequency limits and input voltage ranges. Consider thermal management capabilities given the wide operating temperature span. Assess compatibility with existing PCB footprints for SOIC-8 packages. Review lifecycle status carefully due to potential end-of-life implications for long-term production runs.
