NCP1361EABAYSNT1G Description

Short technical summary and product information.

The NCP1361EABAYSNT1G is an offline switch flyback controller from ON Semiconductor, designed for AC-DC power conversion applications. It integrates a high-voltage startup circuit with a typical startup voltage of 560 V and a low startup current of 2.5 mA. The device operates from a VCC supply range of 6.5 V to 28 V, with a startup voltage of 18 V. It delivers up to 20 W of output power and supports a maximum switching frequency of 110 kHz.

 

The controller features cycle-by-cycle peak current limiting and ±10% current regulation for accurate output control. It includes over-voltage and under-voltage output protection, as well as fault protection such as current limiting, over voltage, and short circuit. The no-load power consumption is less than 30 mW at high line, making it suitable for energy-efficient designs. The operating junction temperature range is -40°C to 125°C.

 

The NCP1361EABAYSNT1G is housed in a 6-lead TSOP package for surface mount assembly. It is ideal for flyback converters in applications such as adapters, chargers, and auxiliary power supplies. The device's wide VCC range and robust protection features simplify design and improve reliability.
