NCP1380DDR2G Description

Short technical summary and product information.

The NCP1380DDR2G from ON Semiconductor is a high-performance quasi-resonant current-mode controller for 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 designed for applications requiring stable operation and efficiency, particularly in high-power AC-DC converters for TVs and set-top boxes, as well as offline adapters.

 

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 within an extended VCC range up to 28 V. The NCP1380DDR2G is housed in an 8-SOIC package suitable for surface mounting.

 

This controller supports various protection features, including combined overvoltage and overtemperature protection (for A and B versions) or combined brown-out/overvoltage protection (for C and D versions). Its design is well-suited for adapter applications and contributes to extremely low no-load standby power. The operating temperature range is -40°C to 150°C (TJ).
