DC-DC converters are a class of power supply circuits that convert direct current (DC) from one voltage level to another. The REC3-4815SRWZ/H4/A/SMD-R is a switching-type DC-DC converter designed for a variety of power applications. It is a three-terminal, dual-output device that offers very low voltage drop, high power efficiency, and excellent noise immunity. It is available in a small SOIC package, making it suitable for space-constrained products.

The REC3-4815SRWZ/H4/A/SMD-R is an ideal choice for various power requirements, such as automotive, computer, consumer, and communications applications. It has a wide input voltage range of 4V to 18V, and can deliver an adjustable output voltage of between 0.3V and 5V. It has adjustable step-down current limits of up to 15A, and provides high-efficiency (up to 95%) power conversion and low output voltage ripple, resulting in extended battery life.

The REC3-4815SRWZ/H4/A/SMD-R DC-DC converter features an integrated MOSFET switch. This MOSFET switch turns on and off at preset intervals to regulate the output voltage, as determined by a control loop. The control loop is composed of an error amplifier, a reference voltage, and a comparator. When the output voltage exceeds the reference voltage, the comparator switches the MOSFET off, reducing the voltage at the output. When the output voltage is below the reference voltage, the switch turns on, increasing the voltage at the output. The switching frequency can be adjusted via a resistor connected to the control line of the device.

For optimum efficiency, the REC3-4815SRWZ/H4/A/SMD-R features an auto-skip mode, which reduces the switching of the power MOSFET device when the input voltage is low. This helps to reduce unwanted losses, resulting in improved overall efficiency. The device also features over-temperature protection, over-voltage protection, short circuit protection, current limiting, and soft-start functions. This makes it suitable for a wide range of power applications.

The REC3-4815SRWZ/H4/A/SMD-R is a versatile DC-DC converter solution for a variety of power requirements. It is capable of delivering up to 15A of output current, with high efficiency, low output voltage ripple, and very low voltage drop. It is available in a small SOIC package, making it suitable for space-constrained products, and it features built-in protection functions for improved robustness and reliability. For these reasons, it is an attractive choice for power applications in the automotive, consumer, computer, and communications markets.
