The NCP81061MNTWG from ON Semiconductor is a high-performance, dual MOSFET gate driver optimized for synchronous buck power applications. This advanced driver is designed to complement high-frequency, high-efficiency DC/DC converters that use N-channel MOSFETs in their power stage.

Key Features

• High Drive Capability: The NCP81061MNTWG offers a robust 4.0 A peak source and 4.0 A peak sink current, ensuring efficient charging and discharging of the gate capacitance of large power MOSFETs, which is crucial for high-frequency switching applications.
• Adaptive Dead Time Control: This feature helps to minimize body diode conduction losses by automatically adjusting the dead time between the turn-off of one MOSFET and the turn-on of the other.
• Tri-State PWM Input: The driver supports tri-state PWM input for precision control, allowing for easy interfacing with modern controllers.
• Under-Voltage Lockout (UVLO): Both high-side and low-side drivers are protected by an under-voltage lockout feature, which ensures the device operates only when it is within the safe voltage range.
• Cross-Conduction Prevention: The NCP81061MNTWG is engineered to prevent cross-conduction and shoot-through in the power stage, enhancing system reliability and performance.

Applications

The NCP81061MNTWG is ideal for a wide range of applications including:

• Desktop and Notebook Computers
