NCP4318BLCDR2G Description

Short technical summary and product information.

The NCP4318BLCDR2G is an advanced synchronous rectification (SR) controller from ON Semiconductor, specifically designed for LLC resonant converters with minimal external components. It features two gate drivers for SR MOSFETs, each with independent drain and source sensing pins. The controller incorporates advanced adaptive dead time control to minimize body diode conduction and maximize system efficiency.

 

Key electrical specifications include a wide operating supply voltage range from 6.5 V to 35 V and a wide operating frequency range from 22 kHz to 500 kHz. It provides 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. The device also offers adaptive gate voltage options of 6 V and 10 V, and a low operating current of 100 µA in Green Mode.

 

This controller 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. It is available in SOIC-8 and SOIC-8 EP packages and is Pb-Free and RoHS compliant.

 

The NCP4318BLCDR2G supports features like mixed-mode SR turn-off control, anti-shoot-through control, SR current inversion detection, and soft start functionality. Its advanced turn-off control algorithm ensures stable SR operation across the entire load range.
