NCP12510ASN65T1G

AC DC Converters, Offline Switchers Overview

The NCP12510ASN65T1G is a current-mode PWM controller for offline flyback converters, housed in a TSOP-6 package. It operates with a fixed 65 kHz switching frequency and supports a Vcc supply range of 8.9 V to 35 V. The device features a maximum duty cycle of 84% and delivers up to 6 A of drive current. It includes integrated protections such as overvoltage protection (OVP), overpower protection (OPP), and timer-based short-circuit protection (SCP).

AC DC Converters, Offline Switchers Feature Summary

• Integrated overvoltage protection (OVP) with auto-recovery capability on the Vcc line.
• Proprietary overpowered protection (OPP) allowing full power utilization without affecting standby performance.
• Timer-based short-circuit protection (SCP) for precise trip point selection independent of winding coupling.
• Automatic frequency foldback and skip-cycle operation for enhanced light-load efficiency.

AC DC Converters, Offline Switchers Applications

• Offline flyback power supplies
• AC-DC converter designs
• Adapters requiring high efficiency at light loads

AC DC Converters, Offline Switchers Procurement Notes

Verify the specific suffix 'ASN65' confirms the 65 kHz frequency variant. Confirm the TSOP-6 package type matches your PCB footprint requirements. Check for any recent Product Change Notices (PCN) regarding manufacturing site or material changes. Ensure compatibility with your target voltage range of 8.9 V to 35 V.
