ON Semiconductor ADP3418KRZ Dual Bootstrapped, 12 V MOSFET Driver with Output Disable

The ADP3418KRZ is a high-performance, dual non-inverting MOSFET driver designed by ON Semiconductor, optimized for driving two N-channel MOSFETs, the switches typically used in synchronous buck power converters. This integrated circuit (IC) is particularly suitable for high-density power applications where efficiency and reliability are of utmost importance.

Featuring a dual bootstrapped 12 V driver with true-output disable function, the ADP3418KRZ provides a robust solution for controlling power MOSFETs. The driver is capable of operating at high frequencies, which enables the design of power supplies with excellent transient response, reduced size, and improved efficiency. Its high current drive capability ensures fast charging and discharging of the gate capacitance of the MOSFETs, leading to reduced switching losses and improved overall performance of the power converter.

The ADP3418KRZ boasts a wide supply voltage range, typically from 10 V to 20 V, making it versatile for a variety of applications. The IC's true-output disable feature allows the user to turn off both driver outputs simultaneously, which is particularly useful during system fault conditions or during initial power-up sequences.

Other key features of the ADP3418KRZ include an under-voltage lockout for both channels, which prevents the MOSFETs from operating at insufficient gate voltages, thus protecting the device and the power system. Additionally, the IC offers cross-conduction prevention logic, ensuring that both upper and lower MOSFETs are not conducting simultaneously and preventing potentially damaging shoot-through currents.

The ADP3418KRZ is packaged in a compact, thermally efficient 16-lead SOIC package, which minimizes board space and facilitates heat dissipation. This makes the driver IC an excellent choice for space-constrained applications such as notebook computers, telecommunication equipment, and portable electronics.

Engineers and designers seeking a reliable and high-performance solution for their power conversion circuits will find the ON Semiconductor ADP3418KRZ to be an indispensable component that delivers both performance and efficiency.
