DC DC Converters

DC DC converters allow the user to convert direct current (DC) from one voltage to another. It is a valuable tool for any electronics user who needs to step up or step down their current power source. A variety of configurations are available, including stepped-up, stepped-down, buck-boost, or inverting. Generally, the DC DC converter is an isolated power supply that includes an input filter, a switchmode regulator circuit, and an output filter.

The RW-1205S/SMD isolated DC DC converter is a high efficiency, low profile, step down (buck) module designed for use in industrial, medical, and automotive applications. The RW-1205S/SMD is an ultra-thin, water-resistant, surface-mountable component that can be easily placed within tight spaces. As such, it is well-suited for applications where reliability is paramount.

The RW-1205S/SMD offers a wide input voltage range (4.5V to 60V) with excellent line and load regulation. In addition, the input and output currents are maintained at a set point of 600mA to meet the most demanding application requirements. The converter also features overvoltage, current limit, thermal shutdown, and short circuit protection.

Application Field:

The RW-1205S/SMD is well-suited for a variety of applications where efficiency, power density, and reliability are paramount. Applications include industrial control circuitry, personal computers, medical equipment, and automotive equipment. This isolated, DC DC converter is perfect for powering precision tools and high performance equipment.

Working Principle:

The RW-1205S/SMD utilizes a two-stage topology–it is a combination of a step-up/down converter and synchronous rectification with a high-efficiency switch-mode regulator. The input voltage is converted into current and stored in a magnetic inductor. This current is then converted into a DC voltage which is regulated by the switch-mode regulator.

The switch-mode regulator consists of an input voltage supply, a switch (semiconductor), an output voltage supply, and a control circuit. The input voltage supply passes current through the switch at the frequency of the oscillator. The output voltage supply collects the current created by the switch’s opening and closing. The control circuit adjusts the current flow to output the desired voltage.

The RW-1205S/SMD’s output is regulated by a low-dropout linear regulator connected to the output stage. This greatly enhances the efficiency of the converter. The output of the linear regulator is compared against the reference voltage, and any discrepancies are corrected with the help of two current sources. This regulation ensures that the output voltage remains constant, despite changes in the input voltage.

The RW-1205S/SMD also features several protective functions including over-voltage protection (OVP), current limit protection (CLP), and short-circuit protection (SCP). The OVP circuit will disable the supply if the output voltage exceeds a preset limit. The CLP circuitry limits the output current to a safe level. Finally, the SCP circuitry shuts down the converter if an uncontrolled short circuit occurs.

The RW-1205S/SMD is a reliable and efficient DC DC converter that provides precision and power for a variety of applications. It is an ideal solution for industrial control and automotive electronics.
