The ISL9016IRUFBZ-T is a Dual-Input Buck-Boost Mode Limited Power Source (LPS) Regulator. The device includes integrated buck and boost voltage converters, integrated low IQ 7A million cycle internal power switches with optional external components, and integrated current sensing function. It is suitable for applications that require multiple input sources, such as a combination of battery and AC/DC mains, and offer a high price/performance ratio.

It covers output voltage ranges from 3.3V to 14V and is capable of extending the battery lifetime, protecting the circuit and improving system performance. The linear regulator is easy to use and requires only a few external components. It also features an input voltage range of 2.5V to 16V, up to 95% efficiency and a switching frequency of 1.2MHz.

The regulator is based on a proprietary topology, which allows ultra-low quiescent current (5µA) and 1µA shutdown mode together with thermal shutdown protection, under-voltage lockout (UVLO), over-voltage protection (OVP), active current limiting and robust inrush current control. The wide input voltage range and its high efficiency not only make the device suitable for various applications but also reduce power dissipation and power consumption.

The active current-limiting feature enables the regulator to limit its output current to the preset level during an overload condition. This feature provides additional protection against short-circuits, thus increasing the reliability of the system by protecting the downstream components. The current limiting circuit operates in auto-restart mode, with the output voltage and current limitation automatically reset when the fault has been corrected.

The ISL9016IRUFBZ-T offers a wide variety of package options, including the traditional 5-lead SOT-23, 8-lead SOIC, 8-lead MSOP and 3-lead DFN packages. The regulator is ideal for space-constrained applications and offers flexibility in power-supply design.

The ISL9016IRUFBZ-T is widely used in a variety of applications including mobile phones, tablet PCs, PDAs, notebook PCs, digital cameras, digital televisions, cable box, LCD monitors, medical and automotive systems. It is suitable for power supplies, battery charger, USB port, audio/video supplies and other portable systems.

The working principle of the ISL9016IRUFBZ-T is based on the buck-boost topology, where the input voltage is reduced to the desired output voltage. It is a variation of the buck converter, where the output voltage is lower than the input voltage. In the "boost" mode, the input voltage is higher than the output voltage. The converter operates in one of the two modes depending on whether the input voltage is greater than or equal to the output voltage.

In buck mode, an inductor and an output capacitor store energy in the ON-time. During the OFF-time, the energy stored in the inductor is transferred to the output capacitor, providing a regulated output voltage. When the input voltage is higher than the output voltage, the converter switches to boost mode. In boost mode, the inductor stores energy during the ON-time and during the OFF-time, the stored energy is transferred to the load through the output capacitor.

The ISL9016IRUFBZ-T includes a wide input voltage range and integrated switching functions to meet the power requirements of various applications. It also offers low quiescent current, high efficiency and integrated protection features, making it an ideal choice for power supply designs, where performance and reliability are critical.
