Overview
The NCP1631DR2G is a Power Factor Correction (PFC) controller manufactured by onsemi, designed for critical conduction mode (CRM) and discontinuous conduction mode (DCM) applications. It operates with a fixed switching frequency of 130 kHz and supports a supply voltage range of 10 V to 15 V. The device features an internal startup current of 100 µA and is housed in a 16-SOIC package with a width of 3.90 mm. It functions within an operating temperature range of -40°C to 125°C.
Feature Summary
- Supports both critical conduction mode (CRM) and discontinuous conduction mode (DCM) operation for flexible PFC design.
- Integrates a fixed 130 kHz switching frequency to optimize magnetic component size and efficiency.
- Includes low startup current capability to reduce standby power consumption in connected loads.
Applications
- Power factor correction stages in AC-DC adapters
- LED driver power supplies
- Consumer electronics power management
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and tape specifications. Confirm that the RoHS compliance status matches project requirements. Check the latest product change notices for any material or assembly updates. Ensure the 16-SOIC footprint aligns with the target PCB layout constraints before finalizing procurement.
Selection Notes
Select this component when a CRM/DCM PFC solution is required with a fixed 130 kHz frequency. It is suitable for designs needing a 10 V to 15 V supply range and operation up to 125°C. Consider the 16-SOIC package dimensions for board space limitations. Validate compatibility with the intended input voltage range and output power requirements using official reference designs.
Part Context
The NCP1631 belongs to onsemi's family of power factor correction controllers. It is specifically engineered for high-efficiency AC-DC conversion in compact power supplies. The DR2G suffix indicates surface-mount packaging in a 16-SOIC format. This part addresses the need for simplified control loops in CRM/DCM topologies while maintaining regulatory compliance for harmonic distortion.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-compatibility with existing inventory only through official onsemi engineering channels.
