ADP3418JRZ Dual Bootstrapped, 12 V MOSFET Driver with Output Disable

The ADP3418JRZ from Analog Devices Inc. is a high-performance, dual MOSFET driver optimized for driving two N-channel MOSFETs, the main high-side and the synchronous low-side MOSFETs, in a synchronous buck power converter. It is particularly suitable for CPU power delivery in personal computers, servers, and other voltage regulation applications that require high efficiency and fast switching.

This driver is capable of effectively driving MOSFET gates with voltage levels up to 12 V. The ADP3418JRZ features a bootstrapped high-side drive that operates up to 100% duty cycle, making it highly efficient for continuous operation. The device is designed to minimize driver shoot-through and provides a robust output disable feature that ensures the MOSFETs remain off when necessary, preventing potential damage or power loss.

Key features of the ADP3418JRZ include:

• Bootstrap Operation: Allows for a high-side drive with a duty cycle up to 100%, which is essential for maintaining efficiency in buck converters.
• Output Disable Function: Provides a safe shutdown mode by disabling the outputs, ensuring the MOSFETs are off when required.
• Adaptive Nonoverlap Control: Reduces transition losses by preventing simultaneous conduction of both MOSFETs.
• Fast Propagation Delays: Ensures quick response times, improving the overall performance of the power converter.

The device is housed in a compact SOIC-8 package, making it suitable for space-constrained applications. Its operating temperature range is from -40°C to +85°C, allowing for reliable performance across a wide range of environmental conditions.

With its advanced features and robust design, the ADP3418JRZ MOSFET driver from Analog Devices Inc. is a perfect choice for designers looking to optimize their power conversion systems for efficiency and reliability.
