NCP4302BDR2G Description

Short technical summary and product information.

The NCP4302BDR2G from ON Semiconductor is a versatile secondary side synchronous flyback controller designed for high-efficiency flyback converters. It provides essential control and protection functions for synchronous rectifier operation, enabling significant efficiency improvements in space-conscious applications like adapters and chargers.

 

This controller supports various flyback topologies, including continuous mode (CCM), discontinuous mode (DCM), and quasi-resonant mode (QR). It features true secondary zero current detection, high gate drive currents of 2.5A source/sink, and flexible current sensing options (MOSFET RDS(on) or CS resistor). The device incorporates an accurate TL431 type shunt regulator and an optocoupler driver for a complete secondary-side solution.

 

Key electrical specifications include an operating supply voltage range of 9.2V to 28V and a maximum switching frequency of 250 kHz. The NCP4302B variant offers a low voltage reference of 1.275V with 1% accuracy. It is available in a compact 8-SOIC package, suitable for surface mount applications.

 

Typical applications for the NCP4302BDR2G include notebook adapters, LCD TV adapters, consumer appliances, power over Ethernet, and battery chargers. Its design facilitates implementation in space-constrained power supplies.
