Step Down Switching Regulator

In some cases a zener diode may also be used to stabilise the voltage.

Step down switching regulator.

The output voltage can be set from 1 235 v to 35 v. The most basic form of step down transition is to use a resistor as a potential divider or voltage dropper. Modern step down switching regulators and controllers are available with internal architectures that are optimized for applications that have specific goals such as power savings high efficiency or low cost. As a result step down switch mode converters or as they are more commonly termed buck regulators are widely used.

The high current level is also achieved thanks to an so8 package with exposed frame. Increased power supply reliability with system and ic self protection features. The input voltage can range from 4 5 v to 38 v while the output voltage can be set starting from 0 6 v to v in. Analog devices offers a wide range of switching regulators that operate in step up boost step down buck and inverting modes.

Step down buck regulators analog devices manufactures a broad line of high performance step down buck switching regulator ics and buck switching controller ics with both synchronous and nonsynchronous switches. The switch is typically a mosfet igbt or bjt transistor. Step down switching regulators also called buck converters output a regulated voltage level that is less than the input voltage. The issue with this form of voltage dropper or step down converter is that it is very wasteful in terms of power.

Select your device today. The l5973d is a step down monolithic power switching regulator with a minimum switch current limit of 2 5 a so it is able to deliver more than 2 a dc current to the load depending on the application conditions. These devices are capable of generating a fixed or adjustable output voltage and offer up to 2 a of output current. A buck converter step down converter is a dc to dc power converter which steps down voltage while stepping up current from its input supply to its output load.
