DC-DC step-up module, 3V l 5V 1A Boost Board
Product description:
1 : The United States imported chips , and expansion flow MOS tube .
2: The rated output current is expanded to 1A, the maximum possible output 1.5A, 2A Schottky diode using the remainder recharge.
3 : new design, circuit design does not require electrolytic and tantalum capacitors ( electrolytic capacitor life is short , tantalum capacitors have a risk of explosion ) . Now with the end of the circuit used in ceramic capacitors (MCC) 3 stars.
Ripple is very low, only tens of millivolts , many colleagues have reached a 500 mV ripple large , the equipment will cause an invisible injury, serious work will lead to abnormal or damaged equipment .
4 : The same with a load indicator and voltage indicator ( when the battery voltage is less than 2.7V with a load indicator in the case will be extinguished when the battery voltage is greater than 2.7V with a load indicator light, when no load indicator micro- Liang )
5 : Ultra-small size , 14.1 * 18.8 * 5.5 mm
6 : High- circuit conversion efficiency, high efficiency , when more than 90 % in a single lithium battery is also greater than the minimum efficiency of 80% , unlike some peers efficiency is only 60-70 % efficient.
7: Enter the small power polarity protection , if you battery with protective plate 2A, when you reverse the positive and negative input supply , the protection board will be protected , note that when there is no protection board or the input current is greater than 2A, input reverse polarity protection fail , it will cause damage to the module , remember.
8: Ultra-low quiescent current , the new version , the quiescent current to less than 100 microamps. Connected to the battery without adding switches.
With voltage indication ( input voltage is lower than 2.7V LED indicator off )

Applications
1). DIY a mobile power , only need to pick a battery-powered input , you can output 5V voltage for your cell phone , MP3, MP4, PSP charging , very easy oh.
2 ) In order to power your electronic device when your device requires a 5V power supply when , but you are now in the hands only lithium battery-powered , with this module we can boost directly to 5V, solve your problems.
3 ) before level power supply system, when you do a project when the input is battery powered (1-5V) time , and your system board and requires a 5V regulated power supply , then you choose this module we will be your most good choice , not debug directly on the machine to work , easy to do and efficient power boost .
