DC-DC converters are electronic circuits or electromechanical devices used to convert a source of direct current (DC) from one voltage level to another. The RTM-2405S is a high-performance, isolated DC-DC converter from Infineon Technologies that is designed for a wide range of applications. It provides up to 25 watts of output power in a wide input voltage range of 6.5 - 80 volts. The wide Vin range allows the RTM-2405S to be used in many different types of applications ranging from industrial, automotive, medical, lighting, and consumer segments.

The RTM-2405S is built on a high-performance, advanced Primary-Side Regulated (PSR) topology and offers excellent electromagnetic compatibility. This efficient, isolated power supply ensures high reliability for mobile, industrial, and server applications. It features a band gap voltage regulator integrated on the primary (input) side, thus eliminating the need for an opto-coupler. This eliminates the burden of setting up opto-isolated feedback control solutions and provides better reliability and stability to the system. This also provides for a higher efficiency compared to traditional closed loop control systems.

The RTM-2405S provides wide output voltage ranges. Its output voltage accuracy is improved by using an ultra-wide input voltage range, allowing the system to regulate in the most efficient manner. Its large output set point range can handle input voltages up to 60V, providing flexibility and enabling scalability when facing changing input conditions. Output voltage ranges from 0.6V to 11V, ensuring compatibility with various systems.

The RTM-2405S features wide dynamic range pre-1.0V and ultra-low current operating mode to further improve efficiency. This allows for a very low quiescent current draw, reducing the power losses during operation. It also includes a Pulse Frequency Modulation (PFM) switching waveform, allowing the RTM-2405S to operate at a higher switching frequency when light load conditions are detected. This drives the efficiency up to as much as 94%.

The RTM-2405S features integrated OVP/OTP/FC protection functions to ensure system reliability. Its overvoltage/over temperature protection thresholds are monitored by an external resistor divider. This enables better stability and accuracy of the system than competing DC-DC converters that do not include integrated OVP/OTP/FC protection functions.

The RTM-2405S is designed and manufactured to meet RoHS and UL requirements and is readily applicable in wall adapter and notebook charger applications. Its features ensure that it performs reliably, is highly efficient, and provides a wide set of protection features. The RTM-2405S is a highly efficient, isolated power supply that is ideal for a wide range of applications.
