    dc-dc Boost converter step up module 0.9V ~ 5V l 5V 600MA USB mobile power booster circuit board  

• • Useage:

 • 1.DIY mobile power: When you travel or travel always feel your cell phone, MP3, MP4, PDA, PSP is not enough electricity, and you have extra batteries, you can consider yourself a DIY a mobile power; as long as this module plus your choice of [a section of lithium or 2-3 NiMH] can output 5V voltage for your phone, MP3, MP4, PDA, PSP charging.
• 2. Adjust voltage: If you need different voltage when the power in the product design, the device requires a 5V power supply, then choose this module will be your best choice.
• 3. Power Supply: When your power is very unstable, high and low, but when your device needs 5V supply, and that the choice of this module will be your best choice.
 • 4. Are the power supply modules short-circuit protection? I accidentally entered a short-circuit when in use will burn it?
• A: No short-circuit protection, if you need to short-circuit protection, self-recovery series fuse at the input end..
• Notes: Since some manufacturers for their own interests, will be added in MP3MP4 mobile phones and other products in the identification resistor.
 • So purchase this module, if you find you can not use, please ascertain whether the addition of the identification resistor

Notes:

1 ) This module is a step-up module , the output voltage is greater than the input voltage

2 ) Peak current output current does not exceed 600mA
