The ISL91110IRAZ-T7A is an integrated power management device that provides a variety of benefits to a system designer. As a member of the ISL9110 family, a DC/DC switching voltage regulator, the ISL91110IRAZ-T7A is a cut-of-the-edge product that is designed to meet the power requirements of the most intricate, performance-intensive applications.

Applications of the ISL91110IRAZ-T7A range from automotive electronics, handheld devices, and industrial designs to home gateways and networking equipment, and power systems for medical applications. The device continues to develop as an effective tool in saving power, achieving high efficiency, and reducing system complexity in high-performance compact designs.

The ISL91110IRAZ-T7A is a total solution that features a highly efficient DC/DC switching voltage regulator in a very compact package. It contains a low-voltage differential switching (LVDS) isolated input and an isolated output. The input voltage range can be from 5.5 to 36V. The 5V output voltage is adjustable, and the output current can be up to 13A. The device can achieve up to 98% efficiency, resulting in superior power conversion efficiency.

The working principle of the ISL91110IRAZ-T7A is to switch between input and output voltage levels. The device contains an internal switching regulator circuit that consists of a power transistor, a current-limiting circuit, and a feedback loop. When the voltage level at the output is lower than the input, the feedback loop turns the power transistor on and stays on until the output voltage reaches a preset level. When the output voltage exceeds the set level, the feedback circuit turns the power transistor off, and the current-limiting circuit maintains the current at the set level.

Furthermore, an embedded temperature protection circuit ensures safe operation in extreme conditions, and the device is protected against over-current and short-circuit conditions. The device also includes advanced features such as input under-voltage lockout, power good output signal, and over-temperature protection. Additionally, the device supports variable frequency switching and is capable of operating at up to 1.4MHz switching frequency for higher efficiency and higher output power.

The ISL91110IRAZ-T7A is an extremely versatile device that can be utilized in a number of applications. It is designed to be extremely cost-effective, efficient, easy to use, and compact. The device is also designed to meet stringent safety and EMC standards. All these properties will make the ISL91110IRAZ-T7A a highly desirable solution for engineers designing for demanding applications.
