DC DC Converters

DC to DC converters are electronic devices which convert Direct Current (DC) energy from one voltage level to another. In general, a DC to DC converter receives an input voltage, converts it and outputs a voltage at a different level. This type of equipment is used to ensure that the input voltage is always sufficient to power the equipment that requires it. The REC3-2415SR/H1 is one such model of DC to DC converter.

The REC3-2415SR/H1 is a synchronous step-down voltage converter designed to produce an output voltage of 1.2 or 1.5V from an input range of 4-14V. It uses a two-phase interleaved switching scheme to help reduce input/output ripple and thus noise interference in the power system. The device also has adjustable output current limiting to allow for continuous, current-limited operation even during start-up with a high output capacitance. It features built-in protection against overload, short circuit, under voltage lockout, as well as thermal shutdown for operating temperatures up to 125°C.

The working principle of the REC3-2415SR/H1 is simple. The input signal is used to switch the two complementary power transistors on and off. When the transistors are switched on, current flows from the input source to the output contact helping dissipate energy and charge the output capacitor. When the transistors are switched off, the stored energy stored on the output capacitor is passed through the inductor to the output. This process is repeated until the desired output voltage is achieved.

The primary application fields of the REC3-2415SR/H1 converter are in industrial/automotive electronics, battery packs/chargers and computing/data-center power systems. The compact 4mm x 6mm SOP package offers high integration to design efficient and cost-effective power systems. The device is also suitable for LED drive applications.

In conclusion, the REC3-2415SR/H1 is a synchronous stepdown voltage converter designed for converting a wide range of input voltages up to 14V to an output voltage of 1.2 or 1.5V. It is ideal for use in demanding applications such as industrial/automotive electronics, battery packs/chargers and computing/data-center power systems. The converter also features advanced protection features such as overload protection, undervoltage lockout, and thermal shutdown.
