[Verified] IP5306 module

Real object:

1. Finished product

test:

1. Charging

2. Vout voltage during charging

Because I have to hold the test lead when taking pictures with one hand, the display keeps jumping. In order to facilitate taking pictures, I pressed HOLD. The actual voltage measured by Vout is also this value.

3. Discharge

The LED (labeled TX) under IO19 on the actual blackboard flashes, indicating that the blackboard has voltage input, that is, the IP5306 module has output.

4.Vout voltage when no load

Precautions:

1. IP5306 chip specifications (parameters on the data sheet)

        Input voltage 4.65V~5.5V

        Output voltage 5V, maximum output current 2.4A

2. LED and resistor

        Actually use a white LED (No.: C84265) , coupled with a 2k resistor. I personally think it's still a bit bright.

        You can also directly put a piece of tin on it without resistors. These two resistors are not included in the IP5306 data sheet. I added them myself.

        How to match it depends on yourself.

3. PMOS part

        PMOS actually uses CJ3401 (No.: C13799)

        The resistance of resistor R5 can be increased or decreased as appropriate.

2. Screw hole

       M3 aperture, 3 holes are connected to Vin, Vout and GND respectively! ! !

       If you didn't pay attention to this and destroyed the circuit, don't come to me.
