NCP12700BDNR2G Description

Short technical summary and product information.

The ON Semiconductor NCP12700BDNR2G is a fixed-frequency, peak current mode PWM controller suitable for implementing single-ended power converter topologies like Flyback and Forward converters. It features a wide input voltage range and a programmable oscillator capable of operating from 100 kHz to 1 MHz.

 

Key electrical features include a user-adjustable soft-start ramp, input voltage UVLO protection, and an adjustable Over-Power Protection circuit. The device integrates a 1 A / 2.8 A source/sink gate driver and offers skip cycle mode for low standby power. Fault protection features include cycle-by-cycle peak current limiting, timer-based overload protection, and interfaces for thermal and output over-voltage protection.

 

This controller is available in a 10-MSOP package and is designed for surface mounting. Its operating temperature range is -40°C to 125°C (TJ). The NCP12700BDNR2G is suitable for applications such as telecommunications power converters, industrial power modules, and Power over Ethernet powered devices.
