ISL6594D is a high-frequency MOSFET driver specifically designed to drive upper and lower power N-Channel MOSFETs in a synchronous rectified buck converter topology
The ISL6594D MOSFET driver is designed for synchronous rectified buck converter topologies. It provides dual upper and lower gate drives with a selectable voltage range of 4.5 V to 13.2 V, enabling optimization of efficiency and gate charge. Integrated features include adaptive zero shoot‑through protection, over‑voltage protection, and a three‑state PWM input with a shutdown window.
The device is offered in SOIC‑8 and DFN‑10 packages, supports switching frequencies up to 2 MHz, and operates over an ambient temperature range of 0 °C to +85 °C. Recommended operating conditions, absolute maximum ratings, and detailed pin descriptions are provided for designers.
