Features: IP5328P has constant synchronous switch structure, the constant-voltage rechargeable lithium battery management systems support. It can automatically adapt different charging IP5328P switch using charging techniques, the switching frequency is 500kHz. Ordinary 5V input charge, the maximum input power 10W; fast charge input When charging, the maximum input power of 18W. End of the battery maximum charging current up to 5.0A, the maximum charging efficiency of 94%, the charging time- can be shortened to 3/4. IP5328P support integrated high voltage output of the synchronous switching systems, to support wide voltage range of 5V ~ 12V output, negative Carrying capacities of 5V-3.1A, 7V-2.4A-, 9V-2.0A, 12V-1.5A. Switching frequency 375KHz. Built-in soft startFunction to prevent inrush- current at startup- failure caused by excessive, the integrated output overcurrent, short circuit, overvoltage, overtemperature protection-, Using mobile power core- IP5328P optimized layout, support for multiple protocols fast charging, fast charging bidirectional 18W, can support total charging port 4: 2 USB-A output interface, USB-C- interface, MicroUSB interface; Specifications: Size:approx 65mmx33mm/2.56x1.3in Output Interface: USBA + USBA + TYPE-C support fast charge output (see protocol specification fast charge) An input interface: MICRO+TYPE-C support fast charge input (see protocol specification fast charge) Battery Type: 3.7V battery (lithium battery assemblage- or 18650) Single parallel-, the capacity is not limited, the larger the capacity of charge and discharge time- longer, please add the battery safety protection- board Indicating fast charge: input and output high voltage fast charge indicator Conversion efficiency: 95% efficiency Package Includes: 1PC Fast Charge Switch Module note: Due to the problems of lighting effects and shooting angles, there will be certain tolerances in the product, please understand. Please allow 0-1cm error due to the manual measurment
