For example, it can step 24V down to 5V, or 48V down to 12V. This module uses advanced switching technology to do so with up to 96% efficiency — far superior to linear regulators that simply dissipate excess voltage as heat.\u003c\/p\u003e\n\n\u003ch3\u003eIdeal Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eDIY electronics and maker projects\u003c\/li\u003e\n  \u003cli\u003eRaspberry Pi, Arduino, and microcontroller power supplies\u003c\/li\u003e\n  \u003cli\u003eAutomotive and solar power systems\u003c\/li\u003e\n  \u003cli\u003eLED strip and lighting drivers\u003c\/li\u003e\n  \u003cli\u003eIndustrial control boards and custom PCB designs\u003c\/li\u003e\n  \u003cli\u003eRobotics and drone power management\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eLearn more: \u003ca href=\"https:\/\/www.energystar.gov\/products\" target=\"_blank\" rel=\"noopener\"\u003eENERGY STAR product efficiency guidance\u003c\/a\u003e\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eQ: Can this DC-DC buck module output 5V from a 12V or 24V input?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! This buck converter accepts any input from 7V to 100V DC and can step it down to a fixed 5V output.
