RSS-2409/H-R is a kind of DC-DC converter, and it converts the unregulated DC voltage to regulated DC output voltage. It works with efficiency and reliability, making its application field to be very wide.

Overview

The RSS-2409/H-R DC-DC converter is a high frequency switching power supply, which is designed for open frame applications. The RSS-2409/H-R offers a wide input voltage range of 9~18V and output voltage of 5V/12V @2.4A, and it provides short circuit protection, overvoltage protection and thermal shutdown. It works with high efficiency and with low temperatures. It also provides soft start, short circuit protection, reverse connection protection, overvoltage protection, overcurrent protection, and wide temperature range. These features make RSS-2409/H-R suitable for most of applications. It is widely used for automotive, computing, communication, industrial, and other applications.

Working Principle

The main working principle of RSS-2409/H-R power converter is to use a switching converter to supply an output voltage which is related to an input voltage. It use an inductor and a switch (usually MOSFET) to transfer the power from the input voltage source to the output voltage. The switching circuit works on the principle of synchronous rectification. It turns on the switch, while the inductor is charging, and off while the inductor is discharging, and the charge is transferred from the input voltage source to the output voltage.

This switching converter uses the concept of voltage transformation. The output voltage is regulated through a fixed duty cycle control technique, and this technique is what makes the power supply efficient and reliable. During the switching process, the inductor will store energy in the form of magnetic field, and when the switch turns off, the current will flow from the inductor to the output voltage. The energy stored in the inductor maintains the voltage of the output voltage. In addition, an additional control loop can regulate the output voltage, with the aim of maintaining the output voltage within a certain range.

In addition, the RSS-2409/H-R offers a soft start feature, which is designed to protect the device from overcurrent and overvoltage of the power supply, and to reduce the peak inrush current. It also has protection against output short-circuit and reverse connection.
