NCP1602DFCSNT1G

Overview

The NCP1602DFCSNT1G is an enhanced, high-efficiency power factor correction (PFC) controller manufactured by onsemi. It operates with a fixed switching frequency of 33 kHz and supports critical conduction mode (CRM). The device is housed in a compact TSOP-6 surface-mount package, suitable for space-constrained designs. It functions within a wide operating temperature range from -40°C to +125°C, ensuring reliability in demanding environments. With a low operating supply current of 70 µA and a power dissipation rating of 550 mW, it contributes to efficient system performance.

Feature Summary

• Enhanced efficiency design for improved power factor correction performance
• Supports critical conduction mode (CRM) operation for optimized control
• Integrated protection features ensure robust system reliability

Applications

• Power supplies for consumer electronics
• Adapters and chargers for portable devices
• General-purpose AC/DC conversion systems

Procurement Notes

Verify the specific ordering suffix 'NT1G' corresponds to the required tape-and-reel packaging quantity and RoHS compliance status as defined by onsemi standards. Confirm that the TSOP-6 package dimensions align with your PCB footprint requirements. Ensure the supplier provides valid origin documentation to guarantee component authenticity and traceability throughout the supply chain.

Selection Notes

Select this component when a fixed-frequency CRM PFC solution is required for medium-power applications. The TSOP-6 package offers a compact form factor compared to larger DIP options. Consider the 33 kHz switching frequency for EMI management and the wide temperature range for industrial or automotive-grade environmental conditions where thermal stability is critical.
