NCP4304ADR2G Description

Short technical summary and product information.

The NCP4304ADR2G from On Semiconductor is a versatile controller and driver tailored for synchronous rectification circuitry in switch mode power supplies (SMPS). It is suitable for various topologies including flyback, forward, and Half Bridge Resonant LLC.

Key features include precise true secondary zero current detection with adjustable threshold, automatic parasitic inductance compensation, and a low turn-off delay time of typically 40 ns. The device offers adjustable minimum on and off times, independent of VCC level, to ensure reliable operation and minimize ringing. It provides 5 A/2.5 A peak current sink/source drive capability and operates within a voltage range of 9.5 V to 30 V.

This controller is designed to maximize MOSFET conduction time, enabling further increases in SMPS efficiency. It also features a disable input for standby or low consumption modes and supports a maximum operating frequency of up to 500 kHz. The NCP4304ADR2G is available in an 8-SOIC package, suitable for surface mount applications.

Typical applications include notebook adapters, high power density AC/DC power supplies, gaming consoles, and all SMPS requiring high efficiency.
