Pololu 5V, 9A Step-Down Voltage Regulator D24V90F5 tv-b-gone Max current draw per RGBThis 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
