Input Reverse Polarity Protection: None Connection: Welding Input: IN + Postive, IN-Negative Output: USB Output Applications: DIY a mobile power supply, only need one battery, you can output 5V voltage for your phone, MP3, MP4, PSP charger, very easy. In order to power your electronic devices when your device needs 5V power supply, when you only have lithium battery, this module can be directly step-up to 5V, solve your problems. Material Download Product Features: Module USES table production booster chip chip, high efficiency (maximum 92%), and at the same time, heating power are small, and chip own over-current protection function, can more good protection of the module and level after use of equipment Under-voltage protection function, less than 2.5 V into under-voltage protection condition, can be more good protection battery, avoid excessive discharge and damage Can be modified by fixed resistance adjust output voltage, highest can adjust to 12 v output, but wants to make sure that the output power within the 5w This module USES a TDK laminated ceramic capacitor as the main filtering capacity, can make the output ripple low to 20 mv (5 v1a output cases) Standard USB interface, can general all use USB charging of mobile phones, MP3, MP4 and other equipment, perfect IPHONE support of mobile Note: Formula output :VOUT = (R1/R2 +1v) * 0.6V Default resistance : R1 = 150K R2 = 20K (unit:ohm) By adjusting the voltage of this formula , which is calculated by the formula resistors , R1 or R2 , replace the resistor can be calculated on the desired output voltage The R1, R2 can be removed and replaced with other resistance Example: I want the output voltage is 8V, then want to replace R1 ,Then 8 = (R1/20K +1) * 0.6, calculate R1, put on it ?
