I suggest you to use sepearate Bosst converter IC and charger ic .
for charge you can use :

It has USB Host Detection feature. It will limit the current as well. And another important...
If you are talking about USB port on a computer, You still cannot provide 3A from a USB port even if you enumarete it. It is probably limited with max 500mA. If you are designing a USB client with which needs to enumareting the host you can use FT231X. It can tell you which type of USB host that...
Gain equals 0db in lower frequency. So it behaves like a pole in a particular way. But still have differnces. But in this method zeros can be accepted as poles.
I have caps, but not shown in picture.

No always one of the mosfet fails.
I do not run it for long time.
My plan is run it for 30-40 seconds with an heatsink for beging sure that it is working. After that i will put it on oil. It will be oil cooled.
It burned always in 3-4 seconds when current goes up 50Amps.(Only 1 channel SiC...
Design parameters are listed below
Vin : 120VDC
Vout : 1V to 50V Digitally Adjustable
Iout : 100A (for 1Vto50V)
Vout(Ripple) : %5
Efficiency : > %85
Frequency : ~40khz(actually it is 42khz due to the mcu clock limitations)
Cooling : Oil Cooled
I do not think it is an overvoltage issue. When i...
Hello,
I am developing a 2 phase interleaved buck converter.
Input Voltage : ~ 120VDC
Output Voltage : 1V to 50VDC
Output Current : 100A Max for any voltage(1to50V)
I attached my circuit diagram.
My problems starts when output current rises about 50A.
For below 50A everthings looks...
My system working about 120-140A. If i connect 1-2 A test load, it's affetct will be too small. If i connect smaller loads for high amps their size are too big and prices are expensive.
Secondly,
You are right about monitoring voltage and current but if i use that method i will probably make...
I sad i do not have test load, so i cannot change the current.
Have any idea what can i do ?

I have solved problem with Kelvin (4-wire) Resistance Measurement Circuit.
Kelvin (4-wire) Resistance Measurement...
Thanks. That makes clear something for me. If I know relation between battery internal resistance and capacity, I can calculate internal resistance.
I can integrate battery model in my system and increase my system accurate.
Thanks for your interest.
I think i could not explain my problem clear. I have any test load and i can not change current. CUrrent change up to real load performance.

Here is a product that can do what i want.
Hello,
I am working on a project that will meausre internal resistance of a lead acid battery. I know DC Load Test but my problem starts with Open Circuit Voltage(OCV). My batteries always connected to power source and i cannot switch my batteries and power source.
MY CONNECTION ...
Hello dear friends,
I am using 5V 1A SMPS power supply for power atmel MCU. I made a capacitive touch sensor with MCU but when i power my board on SMPS it is not working regularly. but than i power it on my computer USB Cable. it is working great.
Another interesting point is when i powered...
