PowerBank modulis (step-up iš 3,7-4,2V į 5V) iki 1A (su ličio baterijos apsauga)

The PowerBank Module is a single chip solution designed for mobile power and includes a load management module, a discharge management module, an LED indication module and a protection module. The integrated loading and unloading of MOS 134N3P can be configured. Large load current and large discharge current 1A. 134N3P internal integrated thermostat charging mode, over-temperature protection, overload and over-discharge, output overvoltage protection, output overload protection, output short-circuit protection, and almost all safety features to ensure the safety of the chip and the Lithium-ion battery, while the 134N3P application circuit is simple, only a few components can be achieved for load management and discharge management.
