The ISL8016IR12Z-T harbors a wide range of effective functions and is designed to provide reliable, cost-effective DC-DC power conversion. This device is a contented member of a broad family of PMIC (Power Management ICs) controlling voltage regulation, DC-DC conversion, over-current protection, supervisory circuits, and fan speed control. In particular, the ISL8016IR12Z-T belongs to the Voltage Regulator family, and more specifically to DC DC Switching Regulators.

DC-DC switching regulators are circuits used to convert electric power from one DC voltage level to another. They use a switching element to pulse width modulate the input in order to achieve a desired output voltage. These switching regulators are primarily divided into two categories, Buck (Step-down) and Boost (Step-up), depending upon the application and its desired output voltage.

The ISL8016IR12Z-T belongs to the Boost category and is a monolithic integrated switching regulator device providing a 3.3V output. This integrated regulator operates with efficiencies greater than 92% and features a low quiescent current (operating current) of only 24mA which makes it suitable for portable applications dependent on single Li-ion batteries. The device features a high efficiency low voltage (VL 13V) buck regulator with a wide input range from 3.2V to 24V. The switch-on time for the integrated regulator is 0.7ms and the typical operating current is 100mA. Since the ISL8016IR12Z-T operates in the buck-boost region, it can handle a wide range of inputs and outputs, providing excellent power conversion efficiency. Furthermore, the device provides output current protection which limits the output current to 3A max.

The ISL8016IR12Z-T contains an internal Charge pump circuit, a burst mode operation circuit, a PFM/PWM operation circuit as well as a operating temperature range of -40°C to 85°C. The switching frequency is adjustable, allowing the device to further optimize system performance. The over-current protection circuit monitors and protects the device against faults. Furthermore, the device features an automatic restart circuit which restarts the internal circuit when a short circuit, over-current or thermal shutdown is detected.

The ISL8016IR12Z-T is a cost-effective, reliable DC-DC switching regulator for use in a variety of applications. It is used in such applications as notebook computers and PDAs, DSL gateways, peripheral components and digital camcorders. Furthermore, this device is used for automotive sensing applications, automotive infotainment and industrial automation. With its long list of features and its wide range of input/output voltages and currents, the ISL8016IR12Z-T is a formidable solution for the most demanding applications.
