The NCP4318ALKDR2G from ON Semiconductor is an advanced synchronous rectification (SR) controller specifically designed for LLC resonant converters, requiring minimal external components. It features two independent gate drivers for SR MOSFETs, each with dedicated drain and source sensing pins.
Key electrical specifications include a wide operating supply voltage range from 6.5 V to 35 V and an operating frequency range of 22 kHz to 500 kHz. The controller offers high gate sourcing and sinking current capabilities of 1.5 A and 4.5 A, respectively, with short turn-on and turn-off delay times of 30 ns. It also includes features like advanced adaptive dead time control, SR current inversion detection, and soft start functionality.
This device is suitable for applications such as high power density adapters, large screen LED-TV and OLED-TV power supplies, high efficiency desktop and server power supplies, networking and telecom power supplies, and high power LED lighting. The NCP4318ALKDR2G is supplied in an 8-SOIC package, suitable for surface mount applications.
