NCP12700BMTTXG Description

Short technical summary and product information.

The NCP12700BMTTXG is a fixed-frequency, peak current mode PWM controller from ON Semiconductor, suitable for implementing single-ended power converter topologies like Flyback and Forward converters. It features a wide input voltage range of 9V to 20V and a programmable oscillator capable of operating from 100 kHz to 1 MHz.

 

This controller integrates essential features such as a high-voltage startup regulator, current mode control with slope compensation, and adjustable soft-start. It also includes a suite of protection features including cycle-by-cycle peak current limiting, timer-based overload protection, and interfaces for thermal and output over-voltage protection. The device is available in a 10-WQFN Exposed Pad package and is designed for surface mounting.

 

Key electrical characteristics include an 80% duty cycle, isolated output, and control features like EN, Frequency Control, Soft Start, and Sync. The operating temperature range is -40°C to 125°C (TJ). This component is ideal for applications such as telecommunications power converters, industrial power modules, and power over Ethernet powered devices.
