DC-DC converters are electrical devices which operate on a variety of input voltages and produce a regulated output voltage. The R2S8-2409 DC-DC Converter is a switch-mode power converter from Murata Power Solutions and is primarily intended to operate from a 5V DC input. The R2S8-2409 is a non-isolated DC-DC converter and is designed to be used in a wide variety of applications, including HVAC/R, medical, automotive, industrial, and communications equipment.The R2S8-2409 converter is equipped with a wide range input voltage operating range of 4.3V to 5.5V DC, with a maximum ripple of 20mVp-p and a maximum operating current of 2A. The output voltage is adjustable from 0.9V to 5V DC and can be regulated from 0.1V to 8V DC. The output voltage is also selectable in five steps from 0V DC, 0.5V DC, 2.2V DC, 3.3V DC, and 4.7V DC. The R2S8-2409 converter has a maximum output of 12W and delivers up to 4A of continuous current without external cooling.The R2S8-2409 converter utilizes a synchronous rectification topology, whereby the power switch is driven with a programmable switching frequency. This allows for stable operation over a wide input voltage range and a wide range of operating temperatures. The low switching frequency reduces the losses due to EMI, allowing the converter to meet the strict requirements of medical, automotive, and communications equipment applications. The R2S8-2409 also utilizes a programmable soft-start feature which provides a controlled ramp for the output voltage to reduce inrush current. The patented design of the R2S8-2409 enables the converter to operate in a sub-second load transient response with minimal output voltage shift. The protection features of the R2S8-2409 include over-voltage protection (OVP), under-voltage protection (UVP), current limiting and short-circuit protection (SCP). The R2S8-2409 also has a built-in thermal shutdown feature which protects the device from overheating.In summary, the Murata R2S8-2409 is a highly efficient DC-DC converter specifically designed for high current, low voltage applications. Its low switching frequency, adjustable output voltage, programmable soft-start, and high efficiency make it suitable for a range of applications from HVAC/R, medical, automotive, industrial, and communications to lighting control. With its wide operating temperature range and patented design, the R2S8-2409 is a reliable and long-lasting DC-DC converter ideal for a variety of applications.
