DC DC Converters

DC-DC converters provide power conversion between two voltages with an efficiency that greatly exceeds a linear regulator. They can also employ energy-saving techniques such as remote control, burst-mode operation, synchronization, and changes in high-frequency switching of the output. This article will focus on the RTS-1224/P-R application field and working principle.

Application Field

The RTS-1224/P-R DC-DC converters are ideal for applications such as power supplies for embedded processors and microcontrollers. The RTS-1224/P-R DC-DC converters have a wide operating range of 2.5 V to 12 V, and provide up to 1200 mA of output current. The RTS-1224/P-R DC- DC converters are also capable of being operated up to 85°C and provide a wide temperature range.

Working Principle

The RTS-1224/P-R DC-DC converters operate on a buck-conversion topology, which means that an input voltage is converted to a lower output voltage, typically using a high-frequency switching circuit. When the control pin reaches a certain voltage, the integrated circuit switches off the transistor which grounds the output and stops the current flow.

When the transistor is turned off, the output voltage is recycled back through the coil, however, the stored energy will be converted back into amperage when the transistor is turned on again. This process is repeated at a very high-speed and therefore is the basis of the high-frequency switching circuit. This is the primary reason for the high-efficiency of the DC-DC converter.

The input voltage is regulated using a voltage reference to set the output voltage level. This voltage reference allows for the circuit to maintain its stability and regulation accuracy regardless of any changes in the input voltage. The voltage reference can also be externally adjusted using a potentiometer, allowing for the output voltage to be set at any desired value within the operating range.

Furthermore, the RTS-1224/P-R DC-DC converters have a built-in current-limiter circuit. This circuit limits the maximum amount of current that can be drawn from the output. This makes the DC-DC converters a much safer and reliable choice for embedded projects.

The RTS-1224/P-R DC-DC converters also employ an advanced soft-start circuit, which protects against inrush current and rapid voltage changes. This reduces the output voltage overshoot, and provides a smooth recovery from fault and short circuit.

Overall, the RTS-1224/P-R DC-DC converters are easy to use, reliable, and provide high-efficiency conversion of electrical energy. It is an ideal choice for a range of power supply and voltage regulation applications.
