Other Parts Discussed in Thread: TPS61200
Now I am using TPS61200. A battery supply 4.2V input TPS61200 is 5.5v.
In no-load case, the output voltage has intense jagged shock. When I connected 100R load into system. The output voltage is decreased to 4.2V.
I tried to change capacitor value of C2 or connected 1R resistor after C2. There has no obvious change.
The output voltage with load: (120
Ohm load)
The output without load:
Any suggestions for this case?
