DROK - 090399 Ultra Small Mini DC Power Module DC 3V to 5V 1A USB Battery Converter Step Up Module Charge for MP3/MP4/Phone Samsung Galaxy S3 iPad iPhone 4S 5 6/6 Plus

• Electronic circuit requires no electrolytic capacitors and tantalum and it adopt ceramic capacitor
• Small ripple brings little damage to the board
• Undervoltage indicator: when battery voltage below 2.7V in load, the LED will not light up; when battery voltage less than 2.7V in load, LED will light off; when battery voltage is more than 2.7V without load, LED will in dim light
• Simple wiring connection: connect the IN+ to positive pole of power supply and connect IN- to negative pole of power supply
• Efficiency: Up to 96% (the higher the input voltage, the higher the efficiency)

Feature: <br> Module Properties: non-isolated step-up module <br> Input voltage: DC 1-5V <br> It is better that the input voltage greater than 3V. if the input voltage too low, the module would generate the noises. <br> Output voltage: DC 5.1-5 .2 V <br> Output Current: Rated 1A-1.5A (single lithium input), the maximum 1.5A (single lithium input) <br> Efficiency: Up to 96% (the higher the input voltage, the higher the efficiency) <br> Switching frequency: 500KHz <br> Output ripple: 30mV (MAX) 20M bandwidth (input 4V output 5.1V 1A) <br> Voltage indication: LED lights with load (input voltage less than 2.7V LED indicator off) <br> Operating Temperature: Industrial (-40°c to +85°c) <br> Full load temperature rise: 30°c <br> Load regulation: +/- 1% <br> Voltage regulation: +/- 0.5% <br> Dynamic response speed: 5% 200uS <br> Short circuit protection: None (Please use the lithium battery with protection.) <br> Input Reverse Polarity Protection: None <br> Connection: Welding <br> Input: IN + Postive, IN-Negative <br> Output: USB Output <br> Undervoltage instructions: when voltage below 2.7V, the load LED will not light up <br> <br> Applications: <br> DIY a mobile power supply, only need one battery, you can output 5V voltage for your phone, MP3, MP4, PSP charger, very easy. <br> 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. <br> <br> Package Includes: <br> 1x DC-DC Converter
