TPS2553-Q1: About Max load 1.3A @Rilim=22K

Part Number: TPS2553-Q1

Hello Supporter

In my design, when load 1.3A, the output will drop, and load 0.6A, the output will drop to 4.94V below  5V,  it is right?

    Hi Tseng,

    It's normal to drop as increase the load due to the voltage drop at Rds(on).

    But it seems abnormal for figure3. Why the output voltage has so high and low frequency oscillating value?

    For TI's policy, I will first click resolved button.

    If you have any other concern, contact me any time.

    If you think resolved, please help click 'Issue is solved button'.

    Thanks.
