onsemi Integrated Circuits (ICs) - PMIC - Power Supply Controllers, Monitors NCP4318ALCDR2G

The NCP4318ALCDR2G is an advanced synchronous rectification controller designed for LLC resonant converters, requiring minimal external components. It features two independent gate drivers for synchronous rectifier MOSFETs, each equipped with dedicated drain and source sensing pins. The controller employs advanced adaptive dead time control to enhance efficiency by reducing body diode conduction. It supports a wide operating supply voltage range from 6.5 V to 35 V and operates effectively across a frequency range of 22 kHz to 500 kHz. Key features include mixed mode turn-off control, anti shoot-through protection, low operating current in green mode, and a soft start function. The device is available in SOIC-8 and SOIC-8 EP packages and is compliant with RoHS standards. Applications for the NCP4318ALCDR2G include high power density adapters, power supplies for large screen LED and OLED TVs, desktop and server power supplies, networking and telecom power supplies, and high power LED lighting.
