Renesas Electronics Corporation Gate Drivers ISL6605IR-T

The ISL6605IR-T is a high-frequency gate driver IC designed to drive two N-Channel MOSFETs in synchronous-rectified buck converter applications. It features adaptive shoot-through protection to prevent simultaneous conduction of both MOSFETs, thereby enhancing efficiency and reliability. The driver supports high switching frequencies with a fast output rise and fall time, achieving an ultra-low propagation delay of 8ns. It can handle a load of 3000pF and provides a typical sink current of 4A for the lower gate driver, which helps maintain the gate voltage during rapid phase transitions. The device operates from a single 5V supply and includes an internal bootstrap Schottky diode, simplifying circuit design and reducing component count. Additionally, it incorporates a three-state PWM input for power stage shutdown, which helps prevent negative transients on the output voltage during shutdown. The ISL6605IR-T is available in an 8-lead QFN package, which is compliant with JEDEC standards and offers a compact footprint suitable for high-density PCB layouts. This product is suitable for applications such as core voltage supplies for microprocessors and high-frequency DC/DC converters.
