TP4056 DC-DC Step Up Boost Module 3.7V to 27V Continuously Adjustable - Lithium Li-ion 18650 3.7V 4.2V Battery Charger Board
Mini Boost Converter - USB Output Mini DC - DC Step up Boost Power Converter Module (3V to 5V 1.5A)
Product description: 1. This module is an non isolated step-up/boost converter. It can be used to step up lithium battery ( ~3V ) to 5V USB 2. Applications: DIY a mobile power supply, only need one battery, you can output 5V voltage for your phone, MP3, MP4, PSP charger, very easy 3. In order to power your electronic devices when your device needs 5V power supply, when you only have lithium battery, this module can be used to directly step-up the voltage to 5V Feature: 1. Output ripple: 30mV (MAX) 20M bandwidth (input 4V output 5.1V 1A) 2. Voltage indication: LED lights with load (input voltage less than 2.7V LED indicator off) 3. Operating Temperature: Industrial (-40°c to +85°c) 4. Full load temperature rise: 30°c 5. Quiescent Current: 130uA 6. Load regulation: ± 1% 7. Voltage regulation: ± 0.5% 8. Dynamic response speed: 5% 200uS 9. Short circuit protection: None (Please use the lithium battery with protection.) 10. Input Reverse Polarity Protection: None 11. Connection: Welding 12. Input: IN + Postive, IN-Negative 13. Output: USB Output Specification: 1. Input Voltage Range: 1-5V 2. Output Voltage Range: 5.1-5 .2 V 3. Output Current: Rated 1A-1.5A (single lithium input), the maximum 1.5A (single lithium input) 4. Efficiency: Up to 96% (the higher the input voltage, the higher the efficiency) 5. Switching frequency: 500KHz 6. Output ripple: 30mV (MAX) 20M bandwidth (input 4V output 5.1V 1A)
