The NCP4318AHJDR2G is an advanced synchronous rectifier (SR) controller from On Semiconductor, specifically designed for LLC resonant converters with 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 device offers high gate sourcing and sinking current capabilities of 1.5 A and 4.5 A, respectively. It also provides adaptive gate voltage options of 6 V and 10 V, and a soft start feature with 0 V / 6 V gate output voltage.
This controller incorporates advanced features such as adaptive dead-time control to minimize body diode conduction and maximize system efficiency. It also includes anti-shoot-through control for reliable operation, SR current inversion detection, and multi-level turn-off threshold voltage. The NCP4318AHJDR2G is available in an 8-SOIC package and is suitable for applications like high power density adapters, LED-TV power supplies, and server power supplies.
The device operates within a temperature range of -40°C to 125°C (TJ). Its compact 8-SOIC package is designed for surface mounting.
