A DC DC Converter is a power supply that converts an input direct current (DC) voltage level to a different output DC voltage level, and is used in a variety of applications. The REC5-243.3SRW/H4/C/SMD is an example of a DC DC Converter designed for use in applications with strict space and thermal constraints, specifically targeted for robotic, industrial and medical applications. The REC5-243.3SRW/H4/C/SMD is a single outputDC to DCconverter, offering excellent programming frequency, light load efficiency, low standby current as well as over voltage protection, short circuit protection, over temperature protection and under voltage lockout.

The REC5-243.3SRW/H4/C/SMD DC DC converter employs a unique, patented power conversion technique enabling lower external component count, fewer output inductor turns, and higher efficiency when operating at light load. The architecture also utilizes synchronous rectification, boosting efficiency at full load from 82.5 to 93 percent. This DC DC converter also has an adjustable frequency from 200 kHz to 500 kHz enabling greater flexibility in output ripple and size of inductors.

The REC5-243.3SRW/H4/C/SMD can operate from a 2.7V to 6V input, and is capable of providing up to 25W output power at a fixed output voltage. The converters can deliver an output current of up to 24 Amp, with a 0.18 Ohm input impedance and 0.16 Ohm output impedance. This makes the REC5-243.3SRW/H4/C/SMD ideally suited for a range of ultra-low-power applications in which space and thermal constraints are critical.

The REC5-243.3SRW/H4/C/SMD also features a small form factor and comes in a 5-pin SMD package (nicknamed the "pinky"), measuring in at 3.3 mm x 3.3 mm. Further its efficient topology and low thermal impedance provide the ability to reliably deliver up to 6W of output power from a 2.75 mm x 2.75 mm package at ambient temperatures up to 85°C, making it well-suited for high power density systems.

The working principle of the REC5-243.3SRW/H4/C/SMD is relatively simple. The converter begins by extracting energy from the input DC voltage and storing it in an inductor. An internal switch, typically a MOSFET, then actuates to transfer this energy to the converter’s output. The output voltage is determined by three external components: an inductor, an output capacitor, and a resistor. This three-component network allows for efficient conversion of the input voltage to a fixed voltage output, with an adjustable frequency.

The REC5-243.3SRW/H4/C/SMD is a versatile DC DC converter that is an excellent choice for applications requiring compact size, high efficiency, and light load performance. Its features make it suited for a wide range of applications, including robotics, medical, and industrial. Moreover, its small foot print and robust thermal performance are ideal for designs requiring limited board space and high power density.
