NCP1601AP

Overview

The NCP1601AP is a power factor correction controller designed for discontinuous conduction mode (DCM) and critical conduction mode (CRM). It integrates protection features including overvoltage, undervoltage, overcurrent, and thermal shutdown. The device operates with low startup and standby currents to enhance efficiency in AC adapters and electronic ballasts.

Feature Summary

• Supports DCM and CRM operation modes
• Integrated overvoltage and undervoltage protection
• Programmable overcurrent protection
• Thermal shutdown capability

Applications

• AC adapters
• Electronic ballasts
• TV and monitor power supplies

Procurement Notes

Verify the specific suffix 'A' against the manufacturer datasheet to confirm UVLO hysteresis specifications. Ensure the package type matches the design requirements. Confirm RoHS compliance status through official documentation before procurement.

Selection Notes

Select this component for applications requiring combined DCM and CRM benefits. Consider the fixed frequency DCM for EMI reduction and variable frequency CRM for cost optimization. Evaluate the protection thresholds against system voltage limits.

Part Context

Part of the NCP1601 family offering PFC control solutions. Designed for mid-to-low power applications. Provides a balance between performance and system cost through flexible operating modes.

Replacement Considerations

Check for direct pin-compatible alternatives within the same product family. Verify electrical parameters match the original design requirements before substitution.
