XRP7714ILB-SAQ-F Application Field and Working Principle

XRP7714ILB-SAQ-F is a DC-DC switched mode converter companion IC from ROHM. This integrated circuit (IC) is a member of the ROHM Power Management IC (PMIC) family. Classified as a Voltage Regulator, this specific IC implements the Linear + Switching (Transitional or Buck-Boost) topology. It is built around several linear and non-linear components, such as resistors, capacitors, diodes and transistors, in order to provide a constant DC output voltage, with wide input and output voltage ranges.

Typical Application Schematic

A typical circuit diagram of the XRP7714ILB-SAQ-F application can look like this –

This application circuit contains an input voltage supply VIN (normally 12V or 24VDC) connected to its source pin. At the output of the voltage regulator, you will get your regulated DC output voltage (Vout), according to your intended design.

Working Principle

The XRP7714ILB-SAQ-F uses an adaptive control technology, based on a fast voltage loop with an excessive ripple filter and a sense feedback pin, that allows the output overload and short circuit protection.

The voltage regulator begins its switching process by supplying power to the input node. When the voltage rises to a certain level, as determined by a regulation network, the IC will sense it and start the switching process. At the same time, high-frequency pulses are generated in the loop until the maximum rated output voltage appears. Then, the switching pulses will adjust themselves so as to maintain a desired output voltage, regardless of the load conditions.

The thermal protection feature helps keep the device from exceeding its maximum temperature rating. Internal transistors are short-circuited, safely reducing power supply and preventing catastrophic failure in the event of an overload or short circuit.

Conclusion

The XRP7714ILB-SAQ-F application field consists of DC-DC switches mode converters. By employing its adaptive control technology, it provides constant voltage DC output, with wide input and output voltage ranges. Its excessive ripple filter, sense feedback pin and short circuit protection features offer reliable protection during any condition.
