The ISL91110IINZ-T is a highly efficient DC-DC, synchronous step-down regulator with an output current of up to 10A at an input voltage of up to 14V and an output voltage of up to 2V. It is especially suited for applications in space-constrained designs due to its small size. It is a current-mode switching regulator that is capable of providing up to 95% efficiency. The ISL91110IINZ-T operates at a switching frequency of 2.2MHz which is adjustable through an external resistor. It also has a unique feature which is the variable frequency mode. This feature can be used to reduce power consumption and minimize noise.

The ISL91110IINZ-T is mainly used in power management, such as in consumer and industrial applications. It is designed to be used in battery-powered consumer electronic devices, and can also be used in LED lighting and smart power systems, to mention a few. It is ideal for applications such as USB TypeC PD, data storage, PD charging, motor control and home applications.

The ISL91110IINZ-T works on the principle of hysteretic or synchronous rectification with a current-mode PWM control. The switching frequency is adjustable via an external resistor. Furthermore, the power saving feature of the ISL91110IINZ-T increases efficiency by dynamically reducing the switching frequency. This feature is triggered when the inductor current drops below a certain threshold. The switching frequency reduction can be disabled by setting the PIN_EN pin high, and the switching frequency can be adjusted through an external resistor. The ISL91110IINZ-T also includes an integrated loop compensation feature, which eliminates the need for external compensation components.

The ISL91110IINZ-T also features protection functions such as over current protection, over voltage protection and thermal shutdown protection. The protection functions help to reduce design effort and ultimately improves the reliability of the system. Furthermore, The ISL91110IINZ-T is designed for low electrical noise and is capable of providing an ultra quiet operation.

In summary, the ISL91110IINZ-T is a highly efficient DC-DC, synchronous step-down regulator with an output current of up to 10A at an input voltage of up to 14V and an output voltage of up to 2V. It is suitable for high-power battery-powered consumer electronic devices, LED lighting and smart power systems. It can operate at a switching frequency of 2.2MHz which can be adjustable through an external resistor. It is capable of providing up to 95% efficiency, and includes protection functions such as over current protection, over voltage protection and thermal shutdown protection.
