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, output voltage, and efficiency (see the \u003cem\u003eTypical Efficiency and Output Current\u003c\/em\u003e section below), but the input current can typically be as high as 5 A.

The ENABLE pin can be driven low (under 0.7 V) to put the board into a low-power state. The quiescent current draw in this sleep mode is dominated by the current in the pull-up resistor from ENABLE to VIN and by the reverse-voltage protection circuit, which will draw between 10 µA and 20 µA per volt on VIN when ENABLE is held low . If you do not need this feature, you should leave the ENABLE pin disconnected. Note that like most boost regulators, the input power will pass through to the output when the board is disabled, so the ENABLE pin cannot be used to turn off power to the load. \u003c\/p\u003e\n\n\u003ctable class=\"side_by_side_pics\"\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e\u003ctable class=\"picture_with_caption center\"\u003e\n\n\u003ctr\u003e\u003ctd style=\"max-width: 300px\"\u003e \u003ca href=\"https:\/\/a.pololu-files.com\/picture\/0J4890.1200.jpg?fc0f60a432c29fb0274f7f72b1df1dba\" class=\"noscript-fallback\"\u003e\u003cimg alt=\"\" class=\"zoomable\" data-gallery-pictures=\"[{\" id adjustable step-up voltage regulator u3v50ax with included optional terminal blocks and header pins. data-picture-id=\"0J4890\" data-picture-longest_side=\"800\" src=\"https:\/\/a.pololu-files.com\/picture\/0J4890.300.jpg?fc0f60a432c29fb0274f7f72b1df1dba\"\u003e\u003c\/a\u003e\n\u003c\/td\u003e\u003c\/tr\u003e\n\n\u003ctr\u003e\u003cth style=\"max-width: 300px\"\u003e\u003cp\u003e Pololu adjustable step-up voltage regulator U3V50Ax with included optional terminal blocks and header pins. \u003c\/p\u003e\u003c\/th\u003e\u003c\/tr\u003e\n\n\n\u003c\/table\u003e\u003c\/td\u003e\n\n\u003ctd\u003e\u003ctable class=\"picture_with_caption center\"\u003e\n\n\u003ctr\u003e \u003ctd style=\"max-width: 250px\"\u003e\u003ca href=\"https:\/\/a.pololu-files.com\/picture\/0J4886.1200.jpg?775637942b608406603d0f83d2a1cd01\" class=\"noscript-fallback\"\u003e\u003cimg alt=\"\" class=\"zoomable\" data-gallery-pictures=\"[{\" id adjustable step-up voltage regulator u3v50ahv assembled with included terminal blocks. data-picture-id=\"0J4886\" data-picture-longest_side=\"820\" src=\"https:\/\/a.pololu-files.com\/picture\/0J4886.250.jpg?775637942b608406603d0f83d2a1cd01\"\u003e\u003c\/a\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\n\u003ctr\u003e\u003cth style=\"max-width: 250px\"\u003e\u003cp\u003e Pololu adjustable 9-30V step-up voltage regulator U3V50AHV, assembled with included terminal blocks.\u003c\/p\u003e\u003c\/th\u003e\u003c\/tr\u003e\n\n\n\u003c\/table\u003e\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\n\u003c\/table\u003e\n\n \u003cp\u003eThe connections are labeled on the back side of the PCB, and the board offers several options for making electrical connections.
