The ISL9110AIITNZ-T is a state-of-the-art, high performance, DC-DC switching regulator. It is designed to provide multiple regulated outputs in a single package, thereby saving space and cost in applications. The ISL9110AIITNZ-T is available in a variety of voltage configurations, including 0.8V, 1.3V, 1.8V, 2.5V and 3.3V, which enables its use in a variety of applications.

The ISL9110AIITNZ-T provides a fixed output with a maximum peak current of 5A and a maximum continuous output current of 4A. The peak current limit is adjustable to achieve higher currents. The regulator also has on-chip softstart and enable, as well as local on/off control and programmable soft-start. A low-noise, internal compensation network ensures stable regulation. The ISL9110AIITNZ-T also provides a light load efficiency of up to 90% over a wide input voltage and output voltage range.

The circuit configuration of the ISL9110AIITNZ-T includes an input voltage regulator, a high-side PMOS switch and a low-side NMOS switch that synchronously operate in a continuous conduction mode. The high-side PMOS switch is controlled by an externally supplied PWM signal and the low-side NMOS switch is controlled by the duty cycle of the PWM signal. When the PWM signal is duty cycled, the current through the switches will continuously flow, resulting in a continual output voltage. The ISL9110AIITNZ-T features an adjustable current limit circuit that protects the switches from overcurrent and output overvoltage conditions. The current limit is adjustable between 5A and 10A.

The ISL9110AIITNZ-T is ideally suited for a variety of applications, such as DC-DC converters, power management systems, motor control, and portable electronics devices. It is especially useful in applications requiring multiple output voltages and multiple output currents, while minimizing board space and cost. The ISL9110AIITNZ-T is offered in an industry standard, 24-pin QFN package, making it easy to integrate into existing designs.
