LM2577 High Pressure  DC Booster Module IN3.5-35V OUT5-56V With Indicator  (C3B3)<br />Parameter Description:<br />Input voltage range: 3.5V-35V (make sure to set the output voltage is higher than the input voltage)<br />Output voltage range: 5.0V-56V<br />Input maximum current: 3A (calculated according to the power conservation of output current under nominal conditions<br />Uin * Iin * efficiency = Uout * Iout)<br />Input continuous current: 2A (ventilation condition good output voltage and input voltage ratio is not greater than 3)<br />Dimensions: L * W * H 4.3cm * 3.0cm * 1.2cm<br />Note: When you test if the output voltage is not higher than the input voltage, adjust potentiometer clockwise, the output voltage will rise. Remember, do not try to do counterclockwise adjust antihypertensive module, you must ensure to set the output voltage is higher than the input voltage, so as not to damage the module!<br />IN +: Enter positive, IN-: negative input, OUT +: positive output, OUT-: output negative<br /> <br />Efficiency test as follows:<br /> <br />5V to 12V:<br />5V to 12V = (11.93 * 0.500) / (5.02 * 1.383) * 100% = 86.3% (Because the test didnot consider that the actual output line is more efficient than voltage drop test efficiency)<br />12V switch 24V:<br />12V switch 24V = (23.84 * 0.799) / (12.03 * 1.747) * 100% = 90.7% (Because the test didnot consider that the actual output line is more efficient than voltage drop test efficiency)<br /> <br />Typical applications:<br />1,3.7 turn 5V do mobile charging<br />2, the boost drive LED strings (the need to increase appropriate limiting resistor)<br />3,7.4V boost 12V application HM camera<br />Note: When a large current work will be a lot of heat, please pay attention to strengthening ventilation.<br />LM2577 Boost module * 1<br />Static bag package<br /><img src="//agdetail.image-gmkt.com/m430/095/758/599758095/img/agdetail.image-gmkt.com/095/758/599758095/img/img6.eachbuyer.com/x9/p100/eb4331_1.jpg" />                                                        <img src="//agdetail.image-gmkt.com/m430/095/758/599758095/img/agdetail.image-gmkt.com/095/758/599758095/img/img6.eachbuyer.com/x9/p100/eb4331_2.jpg" />                                                        <img src="//agdetail.image-gmkt.com/m430/095/758/599758095/img/agdetail.image-gmkt.com/095/758/599758095/img/img6.eachbuyer.com/x9/p100/eb4331_3.jpg" />                                                        <img src="//agdetail.image-gmkt.com/m430/095/758/599758095/img/agdetail.image-gmkt.com/095/758/599758095/img/img6.eachbuyer.com/x9/p100/eb4331_4.jpg" />
