Step Down Switching Regulator

The l7985 a is a step down switching regulator with a 2 5 a minimum current limited embedded power mosfet so it is able to deliver up to 2 a current to the load depending on the application conditions.

Step down switching regulator.

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. Select your device today. As a result step down switch mode converters or as they are more commonly termed buck regulators are widely used. Step down switching regulators also called buck converters output a regulated voltage level that is less than the input voltage.

Step down buck switching regulators efficient conversion of an input voltage to a lower output voltage with over 1000 unique devices we own the industry s most comprehensive portfolio of high efficiency dc dc step down buck switching regulators. The issue with this form of voltage dropper or step down converter is that it is very wasteful in terms of power. 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. In some cases a zener diode may also be used to stabilise the voltage.

The switch is typically a mosfet igbt or bjt transistor. Integrated step down switching regulator with pmbus. Increased power supply reliability with system and ic self protection features. Optimized component performance and efficiency with reduced design in time.

Ti offers a broad selection of step down buck dc dc switching regulators to address highly efficient and flexible solution design. The most basic form of step down transition is to use a resistor as a potential divider or voltage dropper. 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.

Some of the features available in adi s portfolio of switching regulators are low battery detector us. Requiring a minimum set of external components the device includes an internal 250 khz switching frequency oscillator that can be externally adjusted up to 1 mhz. 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. 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.

High power density and low component count.
