The ISL91134IIQZ-T is a type of DC to DC switching regulator module that belongs to the family of Power Management Integrated Circuits (PMIC). It is mainly used to increase the voltage of a direct current from one level to another without the need for an external coil or transformer. The device includes all the necessary components to achieve a regulated output voltage, such as an input filter, pulse width modulators (PWM), low-side drivers, and synchronous rectifiers, as well as protection circuits for overvoltage and over-current detection and protection. It also includes integrated circuit (IC) drivers to provide the necessary power. In addition, the ISL91134IIQZ-T comes with a built-in voltage reference circuit, as well as an on-chip delay circuit to ensure a precise output voltage ramp-up.

The ISL91134IIQZ-T is mainly used in applications such as handheld device and battery-operated equipment, automotive audio systems, and storage and communications systems. Its modular construction allows up to four separate power outputs, making it ideal for designs where space is at a premium. The module also features an integrated input filter that eliminates the need for external input capacitors, as well as output filtering components. The device also comes with overvoltage and over-current protection circuits to guarantee safe operation.

The working principle of the ISL91134IIQZ-T is based on the use of pulse width modulators (PWM). The PWM works by rapidly switching the switch MOSFETs "on" and "off" at a certain frequency. During the "on" time, energy is stored in an inductor, which then releases it during the "off" times. This process continues to repeat until the output voltage reaches the desired level. The on-chip voltage feedback circuit then ensures that the output voltage remains under control, while the overvoltage and over-current protection circuits guard against any potential damage.

In conclusion, the ISL91134IIQZ-T is a type of DC to DC switching regulator module that belongs to the family of Power Management Integrated Circuits (PMIC). It is mainly used in applications such as handheld devices and battery-operated equipment, automotive audio systems, and storage and communications systems, and its modular construction allows up to four separate power outputs. The working principle of the ISL91134IIQZ-T is based on the use of pulse width modulators (PWM), and its integrated input filter eliminates the need for external input capacitors. The device also comes with overvoltage and over-current protection circuits, as well as integrated circuit (IC) drivers, to guarantee safe operation.
