Description

This synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 5 V while allowing a typical continuous output current of up to 9 A. Typical efficiencies of 80% to 95% make this regulator well suited for higher-power applications like powering motors or servos, while high efficiencies are maintained at light loads by dynamically changing the switching frequency, and an optional shutdown pin enables a low-power state with a current draw of a few hundred microamps. The regulator's output voltage setting can also be lowered by adding an external resistor.

These high-current step-down (buck) regulators generate a fixed 5 V output from input voltages up to 38 V. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) and have a typical efficiency between 80% to 95%. The available output current is a function of the input voltage and efficiency (see the Typical Efficiency and Output Current section below), but the output current can typically be as high as 9 A.

A very similar version of this regulator is available with a typical maximum output current of 6 A. The two versions of the board are difficult to tell apart visually, so the bottom silkscreen includes a blank space where you can add your own distinguishing marks or labels. You should not use the colors of the printing on the tall, cylindrical electrolytic capacitors to differentiate the two versions as these colors are subject to change. We also carry two much smaller versions of this regulator, one with a typical maximum output current of 2.5 A and one with a typical maximum output current of 5 A.

According to the data, price will be lower in next two weeks, so not waste your money and track better price!

Product review & video

hi and welcome to a new tech stuff episode on my channel and today I'm gonna talk about this little guy here this is a voltage step-down regulator from Pololu I'm gonna show you the installation a short comparison with normal LC filter from Fatshark and I were to show you some footage from DVR recording the difference or a comparison between the fat shark LC filter and pollo step down we'll get ready to how good the picture on your goggles is with this step down the collector so first let's have a look at what we get if you order that unregulated like this here we have some data at 12 volt VI with regulators six hundred milliamps and that's absolutely enough for powering your VTX and your fpv cam that works perfectly in comparison what we have is fat short filter this is a modified version I cut down the size and took off all the connectors which are on the board just to make it smaller
