NCP1380CDR2G Description

Short technical summary and product information.

The NCP1380CDR2G from ON Semiconductor is a high-performance quasi-resonant current-mode controller for high-power universal off-line supplies. It utilizes a proprietary valley-lockout system that reduces switching frequency at lighter loads, improving standby power performance. This controller is suitable for applications requiring isolated power conversion, such as adapters and high-power AC-DC converters for TVs and set-top boxes.

 

Key features include valley switching operation for noise-immune performance, frequency foldback for light load efficiency, and adjustable over-power protection. It also incorporates auto-recovery or latched internal output short-circuit protection with a fixed 80 ms timer. The device offers +500 mA/−800 mA peak current source/sink capability and operates over an extended VCC range up to 28 V. Internal temperature shutdown is also included for safety.

 

The NCP1380CDR2G is housed in an 8-SOIC package and is designed for surface mount applications. It operates within a temperature range of -40°C to 150°C (TJ). The controller supports Flyback topology and provides isolated output.

 

This device is well-suited for adapter applications and features pins for combined overvoltage/overtemperature protection (Versions A and B) or combined brown-out/overvoltage protection (Versions C and D).
