DC DC Converters

DC DC Converters are used to convert direct current from one voltage level to another. The most common type of DC-DC Converters used today is the DC-DC buck converter. The REM6-0512S/A is a DC-DC buck converter that is designed to convert a wide input voltage of 9-36Vdc to a regulated 5V and 12V output.

Application Field

The REM6-0512S/A is widely used in a variety of different applications. It is ideal for use in industrial, medical, communications, and automotive applications which require a high output current in a small package. Due to its wide input voltage range, the converter is able to be used in a variety of different environments, even those with extreme temperatures. Additionally, the REM6-0512S/A is RoHS compliant with no load power consumption of less than 0.1W.

Working Principle

The REM6-0512S/A converter uses a Buck Switching Regulator topology to achieve efficient operation. A buck regulator reduces the input voltage to a lower value regulated by an internal reference voltage. It is a type of DC-DC switching regulator in which the switching frequency and the duty cycle are compared with the internal reference voltage to regulate the output voltage. This type of converter can be controlled by using either a voltage or current mode controller. Current mode controllers are usually preferred because of their greater noise immunity and improved output voltage regulation.

The REM6-0512S/A utilizes a high-side N-channel power MOSFET and a low-side N-channel power MOSFET as the main switching elements. The high-side MOSFET is controlled by a TTL logic level signal to switch on/off the converter. When the high-side MOSFET is on, current flows from the input to the output. The current is then controlled by a piece of feedback circuitry that compares the output voltage to the reference voltage. The low-side MOSFET is used to dissipate the energy stored in the inductor and to provide short circuit protection.

The REM6-0512S/A converter is designed to operate in a range of conditions and temperatures and can meet the most demanding customer requirements. The converter offers a wide input voltage range, up to 36V, which allows for great flexibility when aiming to provide power solutions in multiple applications. It has an adjustable output voltage range between 5V and 12V, and is capable of supplying up to 1.2A of continuous output current. The converter is also designed for high efficiency operation, with a wide operating temperature range of -40℃ to 85℃.

Overall, the REM6-0512S/A is a highly reliable and efficient DC-DC converter that can be used in a wide range of applications. It provides a compact solution to converting both 5V and 12V output voltages in a one-package form factor.
