ISL6740IB Application Field and Working Principle
PMICs (power management integrated circuits) provide voltage regulation and play a critical role in keeping power conversion circuits in top condition. One type of PMIC is the DC-DC switching controller, used to regulate the flow of current in power transistors and other devices in a wide range of applications. The ISL6740IB is a smooth and efficient DC-DC switching controller, manufactured by Intersil Corporation. It is an ultra low power controller that offers a low quiescent current, an input voltage range of 1.5V to 5.5V, and a switching frequency up to 4 MHz.
Applications
The ISL6740IB can be used in many applications, such as notebooks, portable devices, portable disk drives, and wireless communication systems, due to its low power consumption capabilities. It is designed to handle up to 5A of switch current and work on a range of input voltage levels. It also offers a variety of features such as current sense amplifiers, adjustable output voltage, over current and over temperature protection, Low Dropout (LDO) regulator and VOL/VOH control.
Working Principle
The ISL6740IB is designed to regulate the flow of power between an input power source and an output device. The device monitors the output voltage using a voltage divider, and adjusts the duty cycle of an externally provided switching device to stabilise the output voltage. The built-in current sense amplifier and over temperature protection provide excellent protection against shorting or overpowering the circuit. The adjustable voltage output can be set by setting the external resistor. The LDO regulator and VOL/VOH control on the device allow it to work with wider input power sources and better manage dynamic output currents.
Conclusion
The ISL6740IB is an ultra-low power DC-DC switching controller, manufactured by Intersil Corporation. It is designed to provide a smooth, efficient and adjustable voltage regulation for low-power applications. It has a wide range of features, including current sense amplifiers, adjustable output voltage, over current and over temperature protection, Low Dropout (LDO) regulator and VOL/VOH control. With its comprehensive protection and wide range of features, the ISL6740IB is an ideal choice for a range of applications.
