The NCP4318ALCDR2G from On Semiconductor is an advanced synchronous rectification (SR) controller specifically designed for LLC resonant converters. This component minimizes external component requirements and features two independent gate drivers for SR MOSFETs. Its advanced adaptive dead time control compensates for parasitic inductance, reducing body diode conduction and enhancing system efficiency.
The controller supports a wide operating supply voltage range from 6.5 V to 35 V and operates at frequencies between 22 kHz and 500 kHz. Key features include mixed-mode SR turn-off control, anti shoot-through protection, SR current inversion detection, and adaptive gate voltage options. It also offers soft start functionality and short turn-on/turn-off delay times of 30 ns.
The NCP4318ALCDR2G is available in an 8-SOIC package, suitable for surface mounting. Its applications include high power density adapters, LED-TV and OLED-TV power supplies, high efficiency desktop and server power supplies, networking and telecom power supplies, and high power LED lighting.
This device is designed for reliable SR operation over the entire load range, with features like multi-level turn-off threshold voltage and adaptive minimum turn-on time for noise immunity.
