NCP1217AD100R2G Description

Short technical summary and product information.

The NCP1217AD100R2G is a PWM controller from ON Semiconductor designed for AC/DC converters, specifically for flyback topologies. It operates at a fixed frequency of 100kHz and supports an input voltage range of 7.6V to 16V, with a maximum duty cycle of 46.5%.

 

This device features current-mode control with adjustable skip-cycle capability and built-in internal ramp compensation, which helps prevent subharmonic oscillations. It includes auto-recovery internal output short-circuit protection and internal temperature shutdown for enhanced reliability. The controller is housed in a compact 8-SOIC package suitable for surface mounting.

 

Key features include direct optocoupler connection, internal leading edge blanking, and availability of SPICE models for analysis. The NCP1217AD100R2G is designed for applications such as high power AC/DC converters for TVs, set-top boxes, and offline adapters for notebooks.
