DC DC Converters

The RP30-2405DFW DC-DC converter is used mainly for the applications requiring a step-down and a stable DC power supply from a voltage source. It is a surface mount package with a 2:1 wide input range from 9 – 36Vdc, delivering a 24V / 5A output.

Features:

• A wide input range from 9 – 36Vdc
• 24V / 5Aoutput
• Surface mount package
• High efficiency up to 90%
• No load power consumption is less than 0.3 W
• Built-in over voltage / over current / short circuit protections

Working Principle

The RP30-2405DFW DC-DC converter works on the principle of buck converter. Buck converter consists of an inductor electrically connected in series with the input voltage source, a diode in parallel with the load, and a switch in series with the load. The switch is turned on and off periodically to convert the input voltage into a lower output voltage. The frequency and duty cycle of the switch are controlled, depending on the input voltage and output voltage.

When the switch is turned on and the current is increased, the inductor stores energy. When the switch is turned off, this energy is released to the load, causing the current to decrease. The power supplied to the load is controlled by regulating the amount of time the switch is “on”. The switch is generally a MOSFET, which has an on-resistance that needs to be taken into account to minimize the losses.

The most important thing to keep in mind when using the RP30-2405DFW converter is that it must be able to supply sufficient power for the load. That is why it is important to understand the load requirements before selecting this type of converter.
