Summary : 1.1 Name: PW1555 3.3V, 5V, 12V triple input, 1A-4A current limiting chip module with output shortcircuit protection1.2 Application: USB charging products, power supply1.3 Input voltage range: 12V mode: 9V-12.6V; 5V mode: 3.8V-5.4V; 3.3V mode: 2.4V-3.6V. Output≈ input (there is a voltage difference due to internal resistance, and the voltage differenceincreases with the increase of current)1.4 Current limiting setting: Short the corresponding resistor and pad for R1, R2, and R3 accordingto the arrow symbol, and do not short the other two resistors
