Other Parts Discussed in Thread: TPS2121, TPS2120, TPS2113
Hello, here is my setup:
-I use TPS2115 in autoswitching mode
-Two Li-Po batteries are connected at inputs In1 and In2.
-Load current is 0.8A (constant power).
Problem is that hysterisis between input1 and In2 is small, and output begins to oscilate when batteries both about same level. I assume this happens becouse of internal rezistance of the . batteries. Voltage drop occurs on battery and TPS2115 switches to another input. Then situation reapeats..
In my case both inputs must be same priority, but input with higher voltage must be used. Any advice to manually increase hysterisis or use another device to solve this?
