Mini USB Charger DC-DC Step-Up Module Boost Converter for MP3/MP4 Phone Input: 1-5V, Output: 5.1-5.2V #090399 Product Description Feature: Module Properties: non-isolated step-up module (BOOST) input voltage: 1-5V it is better that the input voltage greater than 3V. if the input voltage too low, the module would generate the noises. Output voltage: 5.1-5 .2 V Output Current: Rated 1A-1.5A (single lithium input), the maximum 1.5A (single lithium input) Efficiency: Up to 96% (the higher the input voltage, the higher the efficiency) Switching frequency: 500KHz Output ripple: 30mV (MAX) 20M bandwidth (input 4V output 5.1V 1A) Voltage indication: LED lights with load (input voltage less than 2.7V LED indicator off) Operating Temperature: Industrial (-40°c to +85°c) Full load temperature rise: 30°c Load regulation: ± 1% Voltage regulation: ± 0.5% Dynamic response speed: 5% 200uS Short circuit protection: None (Please use the lithium battery with protection.) Input Reverse Polarity Protection: None Connection: Welding Input: IN + Postive, IN-Negative Output: USB Output Undervoltage instructions: when voltage below 2.7V, the load LED will not light up 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.
