The NCP4303BDR2G from ON Semiconductor is a versatile secondary-side synchronous rectification driver tailored for switch-mode power supplies (SMPS). It is suitable for various topologies including flyback, forward, and Half-Bridge Resonant LLC, enabling high efficiency.
Key features include precise zero current detection, adjustable minimum on/off times to combat ringing, and a fast 40 ns turn-off delay. The device offers a wide operating voltage range of 9.5V to 30V and a peak current sink/source drive capability of 5A/2.5A. It supports a maximum operating frequency of 500 kHz.
Designed for ease of implementation, the NCP4303BDR2G comes in an 8-SOIC package suitable for surface mounting. Its automatic parasitic inductance compensation system maximizes MOSFET conduction time, further enhancing SMPS efficiency. The NCP4303B version features a 6V gate drive voltage clamp, ideal for 24V output applications.
This controller is well-suited for applications demanding high efficiency, such as notebook adapters, high power density AC/DC supplies, and gaming consoles.
