DC DC Converters

The RS-4809D, or Regulated Single Output with Dual Output Power Management, is a DC-DC converter used to convert higher voltage outputs down to outputs suitable for lower voltage applications. This enables its usage in a variety of industrial applications such as automotive, aerospace, medical, and commercial electronics. It offers both low noise, high efficiency, and high isolation.The RS-4809D incorporates patented technology to provide precise regulation, and operates in two steps. The first step is to reduce the higher voltage to a level of 16V to 27V and the second step is to convert this lower voltage into the desired output. In this way, the output is regulated and can always be maintained while providing complete protection from overvoltage conditions.The RS-4809D is highly efficient, with a power dissipation as low as 0.5W and a full-load efficiency of up to 92 percent. It also has an operating temperature range of -40 to +105°C, making it suitable for use in a wide variety of applications.The core of the RS-4809D is its dual-output regulation module, which uses a combination of pulse width modulation (PWM) and switching frequency modulation (SFM) to regulate the output voltage. PWM is the process of using pulses of different intensities to reach the desired output voltage while SFM adjusts the switching frequency in order to improve efficiency. While these features are designed to provide greater accuracy and power efficiency, they also contribute to the low noise output of the RS-4809D.In addition to its regulation module, the RS-4809D also features a series of protections and control features that provide superior reliability and protection. These features include input under-voltage protection, output over-current limiting, and short-circuit protection. Additionally, the RS-4809D offers remote on-off control, and can be triggered with a 5V signal.Overall, the RS-4809D is an excellent choice for DC-DC conversion, and is suitable for a wide variety of applications. With its high efficiency, low noise output, and numerous protection features, the RS-4809D is a reliable, high-performance, and cost-effective solution.
