A trimmer potentiometer lets you set the boost regulator\u2019s output voltage to a value between 2.5 and 9.5 V.<\/p>\n<p><strong>Overview<\/strong><\/p>\n<p>The Pololu adjustable boost regulator is a very flexible switching regulator (also called a switched-mode power supply, SMPS, or DC-to-DC converter) that can generate voltages higher than its input voltage. We offer two adjustable ranges: approximately 2.5 V to 9.5 V and 4 V to 25 V. The output voltage can be set using the trimmer potentiometer in the upper-right corner of the board. The input voltage range is 1.5 V to 16 V (the input voltage should be kept below the output voltage). The integrated 2 A switch allows for output currents high enough to drive small motors, as in our 3pi robot, and allows large voltage gains, such as obtaining 24 V from two NiMH or NiCd cells.<\/p>\n<p><strong>Some example applications include:<\/strong><\/p>\n<ul>\n<li>Powering 5 V or 3.3 V systems from lower-voltage batteries<\/li>\n<li>Powering 5 V subsystems (e.g. sensors) in lower-voltage (e.g. 3.3 V) systems<\/li>\n<li>Achieving consistent actuator operation when powered by fluctuating batteries<\/li>\n<li>Powering high-brightness LEDs or a large number of LEDs in series<\/li>\n<\/ul>\n<p><strong>Note:<\/strong> For high-volume applications, this product can be customized with fixed output voltages ranging from 2 V to 30 V.<\/p>\n<p><strong>Feature Summary<\/strong><\/p>\n<ul>\n<li><strong>Input voltage:<\/strong> 1.5 V to 16 V<\/li>\n<li>Output adjustable from 2.5 V to 9.5 V or 4 V to 25 V<\/li>\n<li>750 kHz switching frequency<\/li>\n<li>2 A switch (and input) limit<\/li>\n<li>Integrated over-temperature and over-current shutoff<\/li>\n<li>Typical efficiency of 80-90% when doubling voltage and with 100-500 mA output<\/li>\n<li><strong>Small size:<\/strong> 10.7 x 22.4 x 5.8 mm (0.42&#8243; x 0.88&#8243; x 0.23&#8243;)<\/li>\n<li><strong>Weight without header pins:<\/strong> 1.6 g (0.06 oz)<\/li>\n<\/ul>\n<p><strong>Don Luc<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Pololu: 791 This powerful, adjustable boost regulator can generate an output voltage as high as 9.5 V from an input voltage as low as 1.5 V, all in a compact, 0.42? x 0.88? x 0.23? package.
