DC DC Converters: R15P205S/R8 Application Field and Working Principle

DC to DC Converters are electronic circuits that convert a direct current (DC) input voltage to a different direct current output voltage. DC to DC converters are also known as DC/DC regulators, voltage regulators, voltage step-up converters, or DC/DC boosters. The R15P205S/R8 is a switching DC-DC converter manufactured in order to provide stable voltage from an unstable source.

Application Field

The R15P205S/R8 is designed to work with a wide variety of applications including but not limited to medical devices, embedded control, automotive, consumer products, and robotics. It is particularly suited to applications requiring boosted voltage and power supply for multiple devices.

The R15P205S/R8 is designed to supply power between 3.5 V to 36 V, and boasts a high efficiency of up to 95%. The device is also available in a tiny 5-pin SOT23 package, making it suitable for a variety of space-constrained projects.

Working Principle

The R15P205S/R8’s working principle is mainly based on the Buck-Boost converter topology. In this topology, the voltage is switched between two values: high and low. During the time the voltage is low, energy is transferred from the source capacitor to the inductor. During the time the voltage is high, the energy stored in the inductor is released to the load. This conversion method is very efficient and can be used to convert a voltage from higher-to-lower, or from lower-to-higher.

The R15P205S/R8 also features an integrated current limit for protection. This current limit will protect the device from over-current/short-circuit on the output and input side. When this happens, the device will be disabled and no output voltage will be supplied. The device can be reactivated by cycling the power.

Conclusion

The R15P205S/R8 is a switching DC-DC converter designed to provide a stable voltage from an unstable source. Its main application field is providing a boosted voltage and power supply for multiple devices. Its operating principle is based on the Buck-Boost topology, which converts a voltage from higher-to-lower or from lower-to-higher. The device also features an integrated current limit for protection. Overall, the R15P205S/R8 is an ideal component for solutions requiring a stable supply from volatile sources.
