NCP1615C2DR2G

Overview

The NCP1615C2DR2G is a Power Factor Correction (PFC) controller designed for critical conduction mode (CrM) operation. It integrates a high-voltage startup circuit and an internal oscillator to regulate the boost converter. The device supports universal AC input voltages and provides cycle-by-cycle current limiting. Key electrical parameters include a supply voltage range of 8V to 30V, a switching frequency range up to 100 kHz, and an operating temperature range from -40°C to +125°C. It features a fixed dead-time control and soft-start capability.

Feature Summary

• Integrated high-voltage startup circuit eliminates external startup resistor requirements
• Critical conduction mode operation optimizes efficiency across load ranges
• Built-in cycle-by-cycle current limiting protects against overcurrent conditions

Applications

• Universal input power supplies
• LED drivers
• Adapters and chargers

Procurement Notes

Verify the complete part number including suffixes such as DR2G for tape and reel packaging and C2 for specific manufacturing codes. Confirm RoHS compliance status through official onsemi documentation. Ensure the ordering code matches the required package type and quantity specifications before finalizing procurement.

Selection Notes

Select this component for applications requiring high power factor correction in critical conduction mode. Consider the integrated startup circuit when designing minimal BOM solutions. Evaluate thermal performance based on the expected operating temperature range and ambient conditions. Verify compatibility with the target boost inductor and output capacitor values.

Part Context

This component belongs to onsemi's PFC controller family focused on cost-effective and efficient power conversion solutions. It is designed to replace older discrete solutions or less integrated controllers. The CrM topology is suitable for medium-power applications where efficiency at light loads is critical.

Replacement Considerations

Check pin-to-pin compatibility with existing designs if substituting other CrM controllers. Verify that alternative parts support the same input voltage range and switching frequency capabilities. Ensure equivalent protection features are present in any replacement component.
