Once the initial specs of a DC-DC design are selected (e.g., input voltage range, output voltage, output current), the first step is to select a converter IC. The desired DC-DC topology will narrow this choice. If the input voltage is greater than the output voltage, choose a buck (i.e., step-down) topology.

DC-DC converters are electronic devices used whenever we want to change DC electrical power efficiently from one voltage level to another. Theyre needed because unlike AC, DC can t simply be stepped up or down using a transformer. In many ways, a DC-DC converter is the DC equivalent of a transformer. Typical applications of DC-DC converters are

DC DC Converter Definition: A DC-to-DC converter is an electronic circuit or electromechanical device that converts a source of direct current (DC) from one voltage level to another. It is a type of electric power converter. Power levels range from very low (small batteries) to very high (high-voltage power transmission).

Because DC/DC step-down (buck) converters feature a controller with one or more integrated FETs and an external inductor, they offer a balance of flexibility and ease of
There are several types of DC-DC converters, each with unique circuit topologies and characteristics. These topologies can be broadly categorized into two groups: non-isolated and isolated converters. Non-isolated converters share a common ground between input and output, while isolated converters provide galvanic isolation between input and
27 · DC-DC Converters convert a direct current voltage input into a different direct current voltage output. They have essentially the same wattage rating on both the input
DC-to-DC converters are placed between the power source (an AC-to-DC converter in this case) and voltage consumers. These circuits help distribute and manage power properly to provide each power consumer with appropriate voltage or current level. It also protects highly-sensitive sub-circuits.

Some DC-DC converters are 90%+ efficient. When using a DC-DC converter, it is good practice to make sure that the source providing power to the DC-DC converter can provide enough power to account for the inefficiency. A good rule of thumb is assume a DC-DC converter is 80% efficient, and then use a source with 125% the load
A power converter is a device that converts one form of energy into another on a continuous basis. A DC-DC converter is an electronic circuit that facilitates the conversion of direct current from one voltage level to another based on the requirements. The DC-DC converter circuits employ high-frequency power conversion using switches
About buck converters. A buck converter, also called buck regulator or DC-DC step-down switching regulator, is a type of DC-DC converter that provides an output regulated voltage that is lower than its input voltage. ST''s monolithic step-down (buck) converter ICs offer input-voltage capability up to 61 V and deliver output currents up to 4 A
DC-DC converter ICs ensure that required voltage is delivered to each circuit due to its own requirements. Converter ICs can both increase or decrease the voltage within the system, by storing the input energy temporarily and then releasing that to the output at a different level. DC-DC converter ICs also regulate the output voltage and
