ON Semiconductor NCP5208DR2G Dual MOSFET Driver

The NCP5208DR2G is a high-performance dual MOSFET driver designed by ON Semiconductor, tailored to meet the demanding requirements of high-frequency, high-efficiency power supplies. This integrated circuit (IC) is engineered to drive two N-channel power MOSFETs in a synchronous buck converter topology, making it an ideal choice for advanced computer processor power supplies, DC-DC converters, and a variety of other power management applications.

Key Features

• High Current Drive Capability: The NCP5208DR2G can deliver up to 2A of peak current for each driver channel, ensuring rapid charging and discharging of the gate capacitance of the MOSFETs, which results in faster switching times and improved overall efficiency.
• Adaptive Non-Overlap Protection: To prevent shoot-through current in the MOSFETs, this driver includes an adaptive non-overlapping circuit that ensures the high-side and low-side MOSFETs do not conduct simultaneously.
• Independent Inputs: The device features independent input pins for each driver channel, providing design flexibility and the ability to optimize the switching times for each phase of the converter.
• Under-Voltage Lockout (UVLO): The built-in UVLO function ensures the driver operates only when the supply voltage is sufficient, thereby protecting the MOSFETs and the load from inadequate gate drive voltage.
• Thermal Shutdown: An integrated thermal shutdown feature safeguards the device from overheating, enhancing the reliability and lifespan of the power supply.

Package and Availability

The NCP5208DR2G comes in a compact, surface-mount SOIC-8 package, which is designed to occupy minimal space on the printed circuit board (PCB) while still offering excellent thermal performance. The device is available in tape and reel format, facilitating easy integration into automated manufacturing processes.

Applications

• Desktop and Laptop Computers
• Graphics Cards
