Overview
The NCP1601BDR2G is a Power Factor Correction (PFC) controller from onsemi, designed for critical conduction mode (CRM) and transition mode applications. It operates within a supply voltage range of 9.6V to 18V and features a switching frequency of 58kHz. The device supports surface mount installation in an 8-SOIC package and functions reliably across a temperature range of -40°C to +125°C. With a startup current of 17 µA, it offers low power consumption during standby conditions.
Feature Summary
- Supports Critical Conduction Mode (CRM) and Transition Mode operation for efficient power factor correction.
- Integrated low-power startup circuitry with minimal quiescent current draw.
- Designed for robust performance across wide industrial operating temperature ranges.
Applications
- Power factor correction stages in AC-DC power supplies
- Adapters and chargers requiring high efficiency
- General purpose offline power conversion systems
Procurement Notes
Verify the exact suffix against official documentation, as the provided model lacks the standard 'G' designation often found in onsemi RoHS-compliant parts. Confirm availability status, as this component may be classified as Not Recommended for New Designs (NRND). Always cross-reference the manufacturer's latest datasheet to ensure pinout and electrical specifications match your design requirements before procurement.
Selection Notes
Select this component for designs requiring CRM PFC control with moderate switching frequencies. Ensure the input voltage range aligns with the 9.6V to 18V supply requirement. Consider thermal management capabilities given the SOIC-8 package constraints. Verify that the 58kHz frequency meets electromagnetic interference (EMI) standards for the target application environment.
Part Context
This part belongs to the NCP1601 series of PFC controllers. It is functionally related to other models in the family, such as the NCP1607BDR2G, which serves as a direct replacement option. The series focuses on cost-effective solutions for power factor correction in consumer and industrial electronics.
Replacement Considerations
The NCP1607BDR2G is listed as a direct replacement for the NCP1601BDR2G. Verify compatibility regarding switching frequency and control modes when substituting.
