The ISL9110AIITAZ-T product is classified as a DC-DC switching regulator, and is a low-cost, high-efficiency power management integrated circuit (PMIC) designed for full 6A power systems. It provides an ideal solution for automotive and energy-sensitive applications that require low quiescent current and ult-low standby power for powered-off modes.

The ISL9110AIITAZ-T enables multiple power rail conversion with one regulator, providing adjustable output voltage regulation from 0.6V to 5.5V with a single power supply. An integrated boost converter provides up to 10V from a single supply when needed. The external power MOSFETs can be arranged in a single-ended or low on-resistance dual-ended topology. In addition, a configurable phase interleaving function allows for current sharing between multiple supplies.

The device also provides an adjustable soft-start function, programmable current limit and thermal shutdown protection, auto-restart that helps make the system compliant with safety requirements, and an over-voltage protection (OVP) to protect system components. Its high switching frequency allows for a small-footprint transformer or inductor, and its low output ripple noise makes the device suitable for noise-sensitive circuits. It also has built-in self-test circuitry to ensure correct system operation. The device is available in a 10-lead DIP and 10-lead SMD package.

The ISL9110AIITAZ-T provides near ideal characteristics for electronic systems, making it ideal for regulated power management applications such as telecommunications, automotive, servers, industrial, and consumer electronics. In particular, it is well suited for small-footprint point-of-load (POL) supply for FPGAs and DSPs, as well as small-footprint processors and precision DAC/ADC power supplies. It can also be used in automotive applications that require high-efficiency and low quiescent current.

The ISL9110AIITAZ-T operates on a fixed frequency, pulse-width-modulated, current-mode switching architecture and provides both step down and step up power conversion in a single IC. A dielectric material prevents leakage of current, while a low on-resistance Power MOSFET reduces conduction losses. The current mode control architecture gives good line and load transient response and allows a much wider output voltage adjustment range than linear regulators. The variable switching frequency enables faster transient response during load changes for optimal system efficiency when required.

The ISL9110AIITAZ-T contains several configurable settings to control its output voltage and inductor ripple current, as well as various protection functions. A user-programmable gain stage and offset compensation loop allows output voltage level and compensation accuracy to be set. A current limit option further prevents excessive current draw, while an overload protection feature will shut off the regulator in case of an overload event. Other features like soft-start, peak current limit and over-voltage protection provide protection against in-rush current, power cycling and device breakdown.

In summary, the ISL9110AIITAZ-T is an excellent PMIC, voltage regulator, and DC-DC switching regulator. It provides a high efficiency, low-cost, and small-footprint solution for a range of power management applications, and is particularly well-suited for automotive and energy-sensitive applications. Its various protection features, adjustable soft-start and configurable settings also make it an ideal choice for many power management applications.
