Application Fields
The ISL8843AABZ is suitable for a wide range of DC/DC converter applications. It can be used in battery-operated and handheld devices, telecommunication systems, automotive systems, and other systems that require high efficiency, overvoltage protection, and accurate current limit. These features make it an ideal solution for power supply systems with space constraints.
Working Principle
The ISL8843AABZ uses a leading-edge pulse-width modulation (PWM) technique to control the output voltage. It is capable of converting a wide input voltage range, from 4V to 36V, into a regulated voltage output. The output voltage is regulated by comparing the feedback voltage to a reference voltage. The frequency of the converter can be adjusted using a resistor. When the feedback voltage exceeds the reference voltage, the controller will reduce the duty cycle and reduce the output voltage. Conversely, when the feedback voltage is lower than the reference voltage, the controller will increase the duty cycle, which in turn will increase the output voltage. The output voltage can also be controlled using an enable pin. The enable pin can be used to turn off the converter in order to save on power consumption when the device is not in use. Additionally, the ISL8843AABZ has built-in protection features such as overvoltage, thermal shutdown, and current limit protection. This provides the added protection needed in modern power supply systems.
Conclusion
The ISL8843AABZ is a DC/DC switching controller from Intersil Corporation. It is designed to convert a wide input voltage range, from 4V to 36V, into a regulated voltage output. It is suitable for a wide range of applications, from handheld devices to automotive systems. It features leading-edge PWM, adjustable frequency, overvoltage protection, thermal shutdown and current limit protection, and an enable pin. The ISL8843AABZ is an ideal solution for power supply systems with space constraints.
