ADP3120AJRZ

Gate Driver Overview

The ADP3120AJRZ is a dual bootstrapped 12 V MOSFET gate driver designed for synchronous buck converters. It integrates high-side and low-side drivers capable of driving a 3000 pF load with a 45 ns propagation delay and 25 ns transition time. The device supports floating top driver designs accommodating VBST voltages up to 35 V, with transient tolerance of 40 V. It features internal adaptive nonoverlap circuitry to prevent simultaneous conduction, undervoltage lockout, and thermal shutdown protection.
