Renesas Electronics Corporation Gate Drivers ISL6605CBZR5168

The ISL6605CBZR5168 is a high-frequency MOSFET driver designed to drive two N-Channel power MOSFETs in synchronous-rectified buck converter applications. It operates with a single low voltage supply of 5V and is optimized for high efficiency at elevated switching frequencies, making it suitable for advanced microprocessor core voltage regulation. This driver features a typical sink current of 4A for the lower gate driver, enabling it to effectively manage high gate capacitance and fast switching times, with an 8ns propagation delay and less than 10ns transition time. The integrated adaptive shoot-through protection prevents both MOSFETs from conducting simultaneously, thereby reducing power loss. Additionally, the ISL6605 includes an internal bootstrap Schottky diode, which simplifies design and reduces costs by allowing the use of cost-effective N-Channel MOSFETs. The device also incorporates a Three-State PWM input that helps prevent negative transients on the output voltage during shutdown, eliminating the need for an external Schottky diode for microprocessor protection. The ISL6605 is available in both SOIC and QFN packages, compliant with RoHS standards, and is suitable for applications such as core voltage supplies for Intel and AMD microprocessors, high-frequency low-profile DC/DC converters, and synchronous rectification for isolated power supplies.
