The ADP3118J is a dual, high voltage MOSFET driver optimized for driving two N-channel MOSFETs, the two switches in a non-isolated synchronous buck power converter. Manufactured by Analog Devices Inc., a leader in high-performance semiconductors, this driver is designed for high-speed, high-frequency applications.

Key Features

• Bootstrapped High-Side Drive: The ADP3118J includes a high-side drive that is bootstrapped, which is ideal for high-side N-channel MOSFET control in configurations such as synchronous buck converters.
• 12 V Gate Drive: It provides a robust 12 V gate drive, which ensures efficient switching of connected MOSFETs, leading to reduced power losses and improved power supply performance.
• Output Disable Function: This feature allows for the quick disabling of the MOSFET outputs, providing a safeguard and control mechanism for various system states and fault conditions.
• Dual Outputs: With dual outputs, the ADP3118J can drive both the high-side and low-side MOSFETs, simplifying the design and reducing component count.
• High Switching Frequency: The device supports high switching frequencies, enabling the design of power supplies with excellent transient response and reduced size due to smaller passive components.

Applications

• Desktop and server VRMs
• Point of load (POL) modules
• High-frequency DC-to-DC converters
• Datacom and telecom power supplies

The ADP3118J is available in a compact 8-lead SOIC package, making it suitable for space-constrained applications while still delivering the performance expected from Analog Devices. Its robust design includes features such as under-voltage lockout (UVLO) for both the high-side and low-side drivers, protecting the device and the power system from operating under sub-optimal voltage conditions.

With its combination of features, the ADP3118J is an excellent choice for power management solutions where efficiency, reliability, and high performance are paramount.
