The NCP81080DR2G is a high-performance, dual MOSFET driver designed and manufactured by ON Semiconductor, a leader in energy-efficient innovations. This advanced driver is tailored to meet the demanding requirements of fast-switching applications, including computing, telecom, and networking equipment. Its compact form factor and efficient design make it an ideal solution for driving N-channel power MOSFETs in synchronous buck converters, which are widely used in point-of-load (POL) modules and voltage regulator modules (VRMs).

Key Features

• High Drive Capability: The NCP81080DR2G is capable of providing high peak current drive, with a 3A sourcing and 2A sinking capability, ensuring rapid charging and discharging of the gate capacitance of MOSFETs for fast switching performance.
• Adaptive Dead Time Control: It features adaptive dead time control that helps to optimize efficiency by minimizing the dead time between the high-side and low-side drives, reducing crossover losses.
• Tri-State PWM Input: The inclusion of a tri-state PWM input allows for easy interfacing with the controller and provides a shutdown feature to ensure safe operation under fault conditions.
• Cross-Conduction Prevention: Built-in cross-conduction prevention logic further enhances system reliability by preventing simultaneous conduction of both MOSFETs.
• Under-Voltage Lockout (UVLO): The NCP81080DR2G is equipped with UVLO protection on both the high-side and low-side drivers, ensuring the device operates only when sufficient supply voltage is present.
