Overview
The NCP1618BDR2G is a high-voltage multi-mode power factor correction controller manufactured by onsemi. It supports continuous conduction mode (CCM) operation with a switching frequency of 65 kHz. The device operates within a supply voltage range of 9.5 V to 35 V and functions reliably across a junction temperature range of -40°C to 125°C. Packaged in a 9-lead SOIC format, it integrates startup current capabilities of approximately 1 mA. This component is designed for efficient power factor correction in AC-DC conversion systems.
Feature Summary
- Supports multi-mode power factor correction strategies including continuous conduction mode.
- Integrates high-voltage startup circuitry for simplified design.
- Operates with fixed switching frequency control for stable performance.
Applications
- AC-DC power adapters
- Electronic ballasts
- Medium power offline converters
Procurement Notes
Verify the specific suffix 'B' against the manufacturer's latest datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the SOIC-9 package dimensions align with your PCB footprint constraints. Confirm RoHS compliance status through official documentation before finalizing procurement.
Selection Notes
Select this component when designing PFC stages requiring multi-mode operation capabilities. Verify that the 9.5 V minimum supply voltage meets your system's brown-in conditions. Ensure the thermal management strategy accommodates the specified operating temperature range up to 125°C for reliable long-term performance.
Part Context
This part belongs to the NCP1618 series of power factor controllers from onsemi. The series is engineered for cost-effective and robust PFC solutions. The BDR2G designation indicates the specific tape-and-reel packaging and lead-free composition suitable for surface-mount assembly processes.
Replacement Considerations
Consult the official onsemi product selection guide for verified cross-reference parts. Ensure any substitute maintains compatible voltage ratings and package dimensions.
