Introduction to DC-DC Converters

A DC-DC converter is a device, which is designed to convert direct current (DC) from one voltage level to another. This makes it extremely useful in a variety of scenarios, such as when supplying distributed power systems, providing voltage conversion for automotive applications, in medical and avionics systems, and in a range of other industrial and consumer applications.DC-DC converters are useful because they allow a higher or lower DC voltage to be output, based on the input voltage. This means that a variety of different devices and systems can be powered or charged with the same power supply – the DC-DC converter is what allows this to happen.

Overview of DC-DC Converters

DC-DC converters are usually comprised of one or more power stages, and are usually either isolated or non-isolated. Isolated converters are typically more expensive, as they add an extra isolated power stage, while non-isolated converters typically do not require this additional stage.The type of power stages used will depend on the specific application, and can be either voltage, current, or frequency-based. In terms of efficiency, DC-DC converters can be generally classified as either linear or switching regulators. Linear regulators provide simple and reliable power conversion, while switching regulators generally offer higher efficiencies, but require more complex circuitry to operate.

RBM-1212S Application Field and Working Principle

The RBM-1212S is a synchronous buck (step down) DC-DC converter specifically designed to provide highly efficient power conversion from a higher to a lower voltage, in a wide range of applications. The RBM-1212S is a current-mode step-down converter with a wide input voltage range from 4.5V to 44V, and an adjustable output voltage from 0.95V to 37V. It is typically used in data systems, communication systems, and medical and industrial systems.The RBM-1212S features an internal high-side switch with either external current sensing or internal current sensing, for precision current and voltage control. The internal current sensing feature eliminates the need for an external sense resistor.The RBM-1212S employs a voltage-mode control technique, which provides fast, accurate, and precise performance even under heavy load transients. The switching frequency on the RBM-1212S is adjustable from 220 kHz to 2.4 MHz, allowing designers to fine-tune the converter for their application.Other features of the RBM-1212S include peak current mode control with programmable peak current level (±25mV accuracy for voltage programming, and ±1% accuracy for current programming); over temperature protection (OTP); input reverse current protection; output short circuit protection; and overvoltage protection (OVP).

Conclusion

In conclusion, the RBM-1212S is a highly efficient, highly reliable synchronous buck DC-DC converter, designed for a wide range of applications. Its wide input voltage range and adjustable output voltage make it ideal for many different kinds of projects, and its over-temperature protection, short-circuit protection, and overvoltage protection ensure safe operation in extreme conditions.
