Part Number: TPS61021EVM-723
Hi everyone,
I'm currently working on a design with this chip. The input is 3.3V and the output is typically 50mA (current driven in MCU). SuperCap is also plugged in the input so when the power is shut down it survives for an additional 20s.
I am having issue with the fact that when said output of the TPS61021 is going in the MCU there is an instability and jittering, while when I'm plugging a passive LOAD (65 ohms so the same 50mA is driven by the chip) there is absolutely no jittering and everything is working fine.
Actually wondering if there is any known solution for this issue
First picture : output on channel 2 with passive Load (65 ohms)
2nd picture : output on channel 2 with MCU as output
