DC-DC converters, such as the REC5-4809SRW/H/B, are electronic devices designed to convert a DC voltage from one voltage to another. The REC5-4809SRW/H/B is a synchronous step-down DC-DC converter. Its wide input voltage range of 2.375V to 11.5V, adjustable output voltage range of 0.75V to 8.5V, and high efficiency of up to 91%, make it ideal for a variety of applications.

The REC5-4809SRW/H/B is widely used in applications such as robots, electric vehicles, communication and power electronics. It can be used to regulate the voltage of batteries, charge controllers and other DC-DC converters as well as providing reliable power to circuits needing voltage of different levels. For example, a power supply for an AC motor in an electric vehicle could use the REC5-4809SRW/H/B.

The REC5-4809SRW/H/B works by converting the input voltage into a pulse waveform that is then regulated to the desired output voltage. The converter employs two methods to accomplish this: pulse width modulation and synchronous rectification. During pulse width modulation (PWM) the switch’s on-time is varied to generate an adjustable average voltage. Synchronous rectification is used to reduce the power losses associated with the conversion of a pulse waveform into a steady voltage.

The REC5-4809SRW/H/B features a user-programmable switching frequency of 200kHz to 1MHz, which allows for a wide range of output voltages. Additionally, it is equipped with a selectable automatic or manual soft-start and enables current mode control of the output voltage, which makes it highly suitable for battery applications. the REC5-4809SRW/H/B also includes a three-state power saving mode, which allows for improved efficiency when light loads are applied.

The REC5-4809SRW/H/B is a robust DC-DC converter suitable for a wide range of applications. Its wide input voltage range and adjustable output voltage range make it ideal for applications that require reliable power of different levels. This makes it a great choice for electric vehicles, robots, communication, and other power electronic applications.
