NCP12400CBAAB0DR2G Description

Short technical summary and product information.

The ON Semiconductor NCP12400CBAAB0DR2G is a fixed-frequency current-mode controller for flyback converters. It features a wide operating voltage range of 10.5V to 28V and operates at a nominal frequency of 65kHz. The device includes various fault protection mechanisms such as Over Load, Over Power, Over Temperature, and Over Voltage.

 

This controller is designed for surface mount applications and comes in a 7-SOIC package. It has a duty cycle of 80% and an operating temperature range of -40°C to 150°C (TJ). The output isolation is specified as isolated, making it suitable for offline power supply designs.

 

Key features include Dynamic Self-Supply, brown-out detection, and frequency foldback for improved light-load efficiency. It also offers a timer-based fault detection and an adjustable overpower protection dependent on the mains voltage.
