IR3584MTRPBF belongs to a special purpose voltage regulator and is suitable for high current and high power applications in industrial, automotive and consumer markets. The regulator is designed to reduce peak input voltages and provide a steady output, as well as protect against over-current conditions on the output. It is capable of regulating wide input voltage ranges, so it can be used in applications requiring single-supply operation.

The maximum output current is 8 A and the maximum output voltage is 16 V. The switching frequency is programmable up to 500 kHz and the switching power is up to 100 W. The external components required for the regulator to function include two key components, one being a low-dropout (LDO) linear regulator and the other an input/output bootstrap diode for buck-boost applications.

The working principle of the regulator is straightforward. The input voltage is compared with the reference voltage and the resultant difference is used to regulate the output voltage. In order to achieve this, the voltage regulator uses current limit, OverTemperature (OT) protection and fault protection circuits. The current limit circuit limits the output current to 8 A, ensuring that the regulator runs safely. The OverTemperature protection circuit monitors the temperature of the regulator and switches it off in the event of an OverTemperature situation. The fault protection circuit monitors the output current and shuts down the regulator if a short-circuit condition is detected.

The regulator can be used in a wide range of applications. It is frequently used in DC/DC converters to regulate the output voltage of the converter. It can also be used in battery-operated consumer electronics such as mobile phones, tablets and laptops. The voltage regulator ensures that these devices operate safely, providing reliable and precise voltage levels.

The IR3584MTRPBF is a versatile and efficient voltage regulator, offering high current and high power capabilities at competitive prices. It has a wide range of applications in industrial and consumer markets and can regulate wide input voltage ranges for single-supply applications. Its ability to protect against over-current conditions and provide a steady output makes it an ideal choice for DC/DC conversion applications.
