The ISL97656IRTZ-T is a sophisticated power management integrated circuit (PMIC) switch mode voltage regulator, designed to provide a programmable output voltage and current for small surface mount packages. As a DC-DC switching power regulator, it is predominantly used for applications that require high efficiency, low noise, and low power losses from their power supply. The device is well suited for a variety of power applications, including low-power 3G basestations and RF modules, as well as medical imaging, instrumentation, and test equipment.

The ISL97656 has a flexible architecture that allows it to be used in a variety of configurations, allowing the designer to customize its performance to the specific application. It includes an adjustable voltage trimming feature, which enables a precise output voltage to be set. The device is capable of a wide range of input and output voltages, both positive and negative, and can support a maximum of 6A output current. It also contains protection functions such as overvoltage and thermal shutdown, which can help protect the device from damage.

The ISL97656 works by allowing current to flow through an inductor in the switched-mode power supply. It then uses the inductor current to generate a waveform which is converted into a programmable output voltage. An integrated switching MOSFET helps to ensure that the output is stable and doesn't oscillate. By controlling the current via an internal voltage reference and external resistor, the output voltage can be adjusted to match the requirements of the application.

Both fixed-frequency and cycle-by-cycle operation are available, enabling designers to select the right mode for their particular application. The device has an ultra-low quiescent current of 350 nA, making it ideal for low-power applications. The high efficiency of the ISL97656 helps to minimize power losses, and the device is designed to minimize electromagnetic interference, helping to ensure compliance with FCC requirements.

The ISL97656 is an ideal solution for applications that require a precise, high-efficiency switch mode DCDC power regulator with low power losses. Its small surface mount package, range of input and output voltages, and low quiescent current make it well suited for a wide range of power applications. Its integrated protection features and ultra-low noise operation are an added benefit for conventional power applications.
