Application Fields
DC-DC converters are used in various applications. The REC7.5-2415DRW/H1/A/M/SMD is applicable in fields which require precise voltage and current control such as automotive, consumer electronics, and industrial systems. It can be used as pre-regulator and post regulator to reduce the load to the input source and reduce the ripple voltage at the output respectively. It is also used as a current source in battery charging applications. Its MOSFET control feature provides fast switching and accurate current control.

The REC7.5-2415DRW/H1/A/M/SMD IC can be used to construct DC-DC converter circuits with wide output voltage range from 0.8V to 10V. It regulates the output voltage with a precision of ±1%. Further, it provides an optimized solution for general purpose buck converter applications over an operating current range of 0.4 A to 5 A. This IC can also be used for multi-channel and single channel applications. It includes several protection features such as thermal shutdown, overcurrent protection, and overvoltage protection.

Working Principle
The working principle of the REC7.5-2415DRW/H1/A/M/SMD is based on buck topology. In this topology, the input voltage is reduced by a switching action before being fed to the load. This reduces power dissipation and increases efficiency. The IC contains a MOSFET driver and MOSFET which act as a switching element. The MOSFET’s gate voltage is controlled by a control stage whose input voltage is compared with an internal voltage reference. The MOSFET is rapidly switched ON/OFF to regulate the current through the inductor to obtain the desired output voltage.

The MOSFET is controlled by a control IC (the REC7.5-2415DRW/H1/A/M/SMD IC). It has an internal voltage reference and error amplifier which compares the output voltage with the reference voltage. When the output voltage is lower than the reference voltage, the error amplifier output increases which in turn increases the gate voltage of the MOSFET and delivers more current to the inductor. The current through the inductor is then increased and the output voltage will be increased. On the other hand, when the output voltage is higher than the reference voltage, the error amplifier output decreases. This reduces the MOSFET gate voltage and the current is reduced. In this way, the output voltage will be regulated at the reference voltage level.

The REC7.5-2415DRW/H1/A/M/SMD IC also contains several other control features such as current limit, short-circuit protection, under-voltage lockout, and thermal shutdown. The current limit control prevents the current from becoming excessive in case of short circuit condition. The under-voltage lockout prevents the IC from staying in ON state when the input voltage is low. The thermal shutdown control minimizes power dissipation and maintains the junction temperature by reducing the current in case of excessive temperature.

In conclusion, the REC7.5-2415DRW/H1/A/M/SMD is a DC-DC converter IC with wide application field. It is suitable for general-purpose buck converter applications and can provide precise output voltage and current control. Its features also provide protection and improve power efficiency.
