Single port 130W mobile power supply IP5389+PL5501-SW2305

Disclaimer in advance: I am not a professional charging player, nor did I major in electronics in college. I majored in music. My electronic knowledge level is probably at the level of P=UI. It was only because a friend gave me two IP5389 chips that I started this project. I also happen to have an 8750H+1050MAXQ tablet and I need to charge it when I go out.

The schematic diagram was drawn by a friend, but his schematic diagram had some problems the first time. Later, I made slight modifications according to the datasheet and succeeded. The PCB was drawn by me. Therefore, there must be some unreasonable aspects in the PCB of this project. You can point it out in the comment area. I am also very willing to learn and improve.

A mobile power main control board designed based on IP5389 and PL5501+SW2305 chips. The default is 5 strings of 4.2V lithium batteries and a 5000mah battery. Single port supports up to 20V 6.5A 130W

Use PD decoy cable to carry ordinary game laptops without stress

There is no IQ tax emark circuit, so I set the maximum power to 65W

Then output different maximum powers by using different current sensing resistors.

You can even use an external driver to make IP5389 run 1KW

IP5389 uses R005 output current sensing resistor by default, set to 65W, and the maximum output is 20V 3.25A 65W

and so on

R004=4.06A 81W

R003=5.41A 108W

R005 parallel connection=6.5A 130W

R002=8.12A 162W

R001=16.25A 325W

PL5501+SW2305 is the same

My component selection:

Power MOS, BSC059N04LS6, because the Ciss of this MOS is very small, basically the smallest I can find with this specification, which can reduce the pressure on the IP5389 driver, also improve efficiency and reduce heat generation.

For the output switch MOS, just use one with low internal resistance, such as Toshiba's TPH series.

Input and output capacitors: Taiwanese and Japanese solid capacitors are sufficient, X5R X7R MLCC from Samsung and TDK

Inductor: WE inductor, because of its good appearance, COPPER and Coilcraft also have good appearance. If you don’t need good looks, you can buy whatever you want. Generally, one-piece ones will be fine. The rated current is recommended to be above 6A, depending on your output power. If possible, you can use LCR to measure the value of the inductance you bought.

Since the power of this board is relatively high, it is recommended to use Samsung 50E, 50G or above battery specifications. If you don’t understand, you can ask friends who play with batteries. I don’t know much about it either. It is recommended not to try high power output for off-brand junk batteries. Don’t blame me if they boom.

This board does not come with battery protection or balancing. Because I am too lazy to solder, I just bought the finished protection board. If you need to integrate it, please add it yourself.

A pink board only used for good looks

However, the arrangement of components will be changed later for better appearance.

Known BUG: IP5389 has built-in power detection. Using another SW2305 will affect the power detection of IP5389.

The following is the input 18V output 20V test

Requires high current TYPE-C connector

At present, I found that KRCONN has 7.5A, but I don’t know how to buy it. If you have any ideas, you can ask.

Changing the current sensing resistor is risky, just don’t overdo it.
