DC DC Converters

DC-DC converters are a type of power adapter that converts a direct current voltage into a desired output voltage level. The R1S-1205 DC-DC converter is a low-cost, low-power module which provides an output of 5V / 200mA.

Application Field

The R1S-1205 DC-DC converter is widely used in consumer electronics, computers, portable audio players, telecommunications, industrial equipment, connections to mobile battery packs, and energy harvesting. It is an excellent choice if you need to regulate current to reduce interference to nearby circuits.

Working Principle

The R1S-1205 works on the principle of controlling the on/off time of a switch. This switch is usually an MOSFET, which is used to control the current in the circuit. The switching frequency is controlled by an internal clock, and the duty cycle is adjusted to make sure that the proper output voltage is maintained.The input voltage is first regulated by a buck-boost converter circuit, which reduces noise, ripple, and voltage fluctuations. This step is important as too much variance in the input will degrade the output voltage.After the input voltage is regulated, the power is sent to a boost converter. The boost converter uses a pair of MOSFETs to increase the voltage, and the output is monitored by a voltage comparator. This comparator is responsible for keeping the output voltage within the desired range. The output of the converter is then sent to the load.

Efficiency

The R1S-1205 is a low-power module and has an efficiency of around 73%. However, if the module is running at full load, its efficiency can go up to around 95%. It is also able to run at very low input voltages, down to as low as 3V.

Conclusion

The R1S-1205 DC-DC converter is an excellent choice for applications that require up to 5V / 200mA of power. It is a low-cost, low-power module and is very efficient. Its wide input voltage range and low ripple means that it is perfect for applications that need clean, consistent power.
