Product Overview
NCP4304ADR2G is a secondary side synchronous rectification driver for high-efficiency SMPS topologies. It is a full-featured controller and driver tailored to control synchronous rectification circuitry in switch mode power supplies. Due to its versatility, it can be used in various topologies such as flyback, forward, and Half Bridge Resonant LLC. The combination of externally adjustable minimum on and off times helps to fight the ringing induced by the PCB layout and other parasitic elements. Therefore, a reliable and noiseless operation of the SR system is ensured. The extremely low turn-off delay time, high sink current capability of the driver, and automatic package parasitic inductance compensation system allow for maximum synchronous rectification MOSFET conduction time that enables further increase of SMPS efficiency. Typical applications include notebook adapters, high power density AC/DC power supplies, gaming consoles, and all SMPS with high efficiency requirements.
- Self-contained control of synchronous rectifier in CCM, DCM, and QR flyback applications
- Precise true secondary zero current detection with adjustable threshold
- Automatic parasitic inductance compensation input
- Typically 40ns turn off delay from current sense input to driver
- Zero current detection pin capability up to 200V
- Disable input to enter standby or low consumption mode
- Adjustable minimum on/off time independent of VCC level
- Low startup and standby current consumption
- SOIC-8 package, maximum junction temperature is 150°C
