DC DC Converters

DC-DC converters are a type of electric power converter which converts direct current (DC) from one voltage level to another. The DC-DC converters mostly step-up, step-down, or produce a higher or lower voltage, current or power with a reduced level of efficiency. They are widely used in various applications such as solar panels, battery-powered appliances, batteries, and thrusters, as well as other mission-critical systems such as medical instruments and avionics.

REC3-2412SR/H1/SMD-R Application Field

The REC3-2412SR/H1/SMD-R DC-DC converter is a highly efficient, ultra-compact, cost-effective, surface-mountable DC-DC converter designed to meet the needs of many mission-critical applications. It features a wide input range of 4.5 to 28V, an adjustable output voltage from 0.6 to 24V and a peak load current of 1.5A. It is suitable for use in a variety of applications, including robotics and electromechanical systems, as well as in general-purpose embedded designs.

REC3-2412SR/H1/SMD-R Working Principle

The REC3-2412SR/H1/SMD-R takes DC input voltage, and through the step-down topology, reduces the voltage to the desired output voltage. The voltage regulation is achieved via an integrated synchronous buck switch, which controls the power supply and continuously adjusts the voltage output to maintain a steady load. The integrated switch is optimized for low noise, switch switching frequency and current losses. This ensures excellent efficiency across the full load range. The output voltage is regulated using the input voltage and the on-board sense resistors.

The REC3-2412SR/H1/SMD-R is designed to operate with an external adjustment potentiometer or an external remote sense resistor, allowing the user to reduce their output voltage level for applications requiring high current at lower loads. Furthermore, the internal protection circuitry ensures that the device does not have any current or voltage overshoots during startup or operation. The device is also available with an optional input UVLO (Under Voltage Lock Out) feature, which protects the device from overvoltage damage and increases its operational reliability.
