DC DC Converters

The RTS-0509-R DC/DC Converter is designed and built to provide a cost-effective solution to convert a 24 to 48 volt DC input to a 5-volt DC output. The unit\'s wide input voltage range allows it to operate in a range of applications, including automotive, renewable energy, medical, and more. The device features built-in over-current and short-circuit protection, thermal shutdown, and ripple voltage specifications that meet EN55022 Class B standards.At its heart, RTS-0509-R is a step-down DC/DC converter with a maximum output current of 9 amps. The converter is based on a current-mode feedback control algorithm, designed to reduce the current variation and output ripple. It also has an input voltage range of 8-40V DC, and is available in a range of versions for various use cases.The device works by continuously converting the input voltage to the output voltage. This is done in a symmetrical manner using Switch-Mode Power Supply (SMPS) circuitry, in which 10 switches modulate the frequency of the output voltage. The output voltage can be adjusted via two digital inputs that control the average output voltage, ensuring the output voltage is as close as possible to the desired voltage.The RTS-0509-R utilizes a synchronous rectification method, which is highly efficient for high-current applications. The device is extremely efficient, achieving power conversion efficiency levels of over 96%. Moreover, it has an adjustable switching frequency of up to 500kHz, meaning that it can supply high-powered applications without requiring excessive cooling measures.In order to ensure the best output stability and the longest lifetime for the converter, RTS-0509-R integrates a cycle-by-cycle current limit and a soft start function in its circuitry. The current limit can be adjusted via two digital inputs, and it ensures that the output current is not higher than the desired maximum current. This helps to protect the converter from overheating and overloading.In addition, the device is designed to provide a very low standby power of 2mW when in OFF mode, making it highly energy-efficient. This is further enhanced by a wide operating temperature range of -40°C to 85°C, meaning that the converter can be used in extreme temperature environments.In conclusion, the RTS-0509-R DC/DC Converter is a highly reliable, cost-effective device for converting 24 to 48V DC input to a 5V DC output. Its wide input voltage range and adjustable switching frequency make it versatile and suitable for a variety of applications. Moreover, its highly efficient step-down switching method and current limit provides greater safety and stability for the device, making it one of the most sought-after converters by many customers.
