Procurement Notes
Verify the obsolete status of this component before procurement. Confirm availability through authorized distributors or check for direct replacement options such as the NCP1607BDR2G. Ensure that any substitute part meets the original electrical specifications and package requirements for your specific design implementation.
Selection Notes
Select this component for CRM and transition mode PFC designs requiring a 58kHz switching frequency. Consider the 8-SOIC package constraints and the 9.6V to 18V operating voltage range. Evaluate the low startup current benefit for efficiency-sensitive applications. Verify compatibility with existing thermal management solutions given the SOIC-8 form factor.
Part Context
This part belongs to the NCP1601 series of power factor correction controllers manufactured by onsemi. It is specifically engineered for cost-effective PFC solutions using critical conduction mode techniques. The series targets applications where high efficiency and reduced component count are prioritized over fixed-frequency operation.
Replacement Considerations
The NCP1607BDR2G is listed as a direct replacement for the NCP1601BDR2G. Verify pinout compatibility and electrical parameter alignment before substitution.
