ISL6525CBZ-T

The ISL6525CBZ-T is a dual-channel, synchronous, high-speed driver for use in DC-DC step-down (buck) converters or other applications requiring high-speed, gate-drive outputs. This driver is specifically designed to drive high peak current and with low propagation delay for shorter switching time. This makes it an excellent fit for applications demanding high efficiency power conversion and reliable performance.

The ISL6525CBZ-T is comprised of an input buffer and two high-current, high-speed gate-drive outputs. It is designed to drive both N-channel and P-channel MOSFETs with up to 15A peak current and provides high peak-current efficiency and improved system reliability. The input buffer eliminates the need for an external logic buffer and allows single-supply operation. It operates over a wide input range, from 5V to 14V. The high-speed outputs feature fast propagation delay and low output impedance, enabling fast transistor switching times.

ISL6525CBZ-T is a DC-DC switching controller used for various application fields such as board level power supply for computing, servers, router and laptop tech, or for portable and battery-powered applications. It can be used for battery charger and backup systems, automotive applications, LED lighting, telecom infrastructure, and industrial motor control of fans, pumps, and other motor control equipment.

The working principle of ISL6525CBZ-T can be divided into three basic stages. First, the current limit and slew rate protection circuitry is enabled for the low-side drivers to protect the associated MOSFETs and the load. Next, the high-side FETs are enabled using the EN_L and EN_H pins. This allows current to flow through the inductor, allowing power to flow from the input to the output. Lastly, the current limit and slew rate protection circuitry is also enabled for the high-side drivers to ensure that the FETs are not over-driven.

ISL6525CBZ-T is a highly efficient DC-DC switching controller for a variety of application fields. It can also support synchronous rectification for greater efficiency. Its input buffer together with the high-speed outputs allow single-supply operation. Its fast propagation delay and low output impedance make it an excellent choice for high efficiency power conversion and reliable performance.
