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.

Hello I wish to use a Pololu 5V, 9A Step-Down Voltage Regulator D24V90F5 to take power from a car battery 12v and power and arduino feather and apa102 strip approx 2meters long.



Is this the correct product to use for this task?



Thanks

Hey Shawn,

Yep, that one will work great!

Just be cautious that APA102 and WS-2812 LED’s use around 20 to 60mA of current each (low/standard brightness with one colour to high brightness full white). Do a quick calculation of 20 x (no. of LED’s) and 60 x (no. of LED’s) and you’ll get roughly what current range you’ll be looking at.

Awesome thanks for the quick reply. 9A will be more than enough :slight_smile:
