USB DC-DC converter 1000mA with Li-ion Charge and Protection circuit

A complete DC-DC converter to boost the Li-ion voltage to 5V USB voltage. This module has a built-in li-ion charge and protection circuit against over- and undervoltage, overtemperature (chip) and short-circuit protection.

This is therefore very suitable to make your own power bank!

Specifications:

• Input voltage (Vin): 5V
• Input current: max 1000 mA
• Battery cut-off voltage: approx. 2.9V
• Battery charge voltage: 4.2V ± 1%
• Output voltage: 5.0V  (USB voltage)
• Efficiency: about 85% (with a li-ion voltage of 3.7V and 5V 1A on the output)
• Output current: max 1000 mA
• Minimum output current: 60mA*
• Standby current: 30μA
• Input: Micro USB connector
• Output: USB-A female connector
• Li-ion connection: Soldering pins (B+ and B -)

* With a lower current the DC-DC converter will turn off into standby mode after about 8 seconds.
