TheISL9104AIRUFZ-T is a dc-dc boost converter specialy designed for the automotive market, aiming to reduce the size and power consumption of automotive power systems. It is a fixed frequency, synchronous step-up converter with integrated high side switches, offering general purpose motors and lighting applications excellent power conversion efficiency and power density. This device also has over-voltage, over-current and short-circuit protection. Therefore, it is classified under DC-DC switching regulators as apart of thePMIC (Power Management Integrated Circuits ) / Voltage Regulators family.

The ISL9104AIRUFZ-T comes with an integrated event-and-sleep timer control which helps reduces power loss during suspend mode. Power can be shut down or be switched to another power source so that energy and money can be saved. This device is also able to power on pulse-by-pulse current mode control. This feature allows for fast current-regulation loop, which increases load step and improves load capability. Furthermore, the ISL9104AIRUFZ-T offers short circuit protection and precise current limit setting, ensuring robust and reliable performance even during overloads.

The working principle of the ISL9104AIRUFZ-Tcan be explained through its architecture and operation. First, power is supplied to the device from an external power source. This power is routed to a start-up circuit that controls the timing and enable the device to start up. From here, power is routed to the control circuitry, and then to the main switch, which is an integrated, high-side MOSFET. When the high-side switch is enabled, it draws current from the input source. This current is then drawn through a synchronous rectifier connected to the output and passed through a feedback pin.

The feedback pin is monitored by the control circuitry and gives feedback to the control circuitry on the output voltage. This feedback voltage is compared to a reference voltage to determine if the output voltage is correct. If the output voltage is too low, the main switch is enabled to increase the output voltage, and if the output voltage is too high, the main switch is disabled to decrease the output voltage. The power switching is done in an abcoulutely synchronous manner, resulting in a step up voltage with high efficiency.

TheISL9104AIRUFZ-Tis suitable for a wide range of applications in general-purpose motors, lighting, automotive, and other portable power systems. It is used to boost up low input voltages, such as 12 volt car battery to 24 volts for automotive power systems. In addition, it has the capability of operating in high temperature and high noise environments, making it ideal for industrial and automotive applications. Its small size and low power consumption make it an attractive option for any application.

In summary, the ISL9104AIRUFZ-Tis a dc-dc boost converter designed for the automotive market with excellent switching efficiency and power density. It is a fixed-frequency, synchronous step-up converter with integrated high-side switches, offering short-circuit protection, over-voltage and over-current protection. It also features an event and sleep timer for low power loss during suspend mode, as well as pulse-by-pulse current mode control to improve load capability. It is suitable for a wide range of applications in general-purpose motors, lighting, automotive, and other portable power systems.
