TPS61027: TPS61020EVM-025 – Output drops during 100 mA → 1 A load transient

Part Number: TPS61027
Other Parts Discussed in Thread: TPS61020EVM-025

Tool/software:

I am testing the TPS61027DRCR using the TPS61020EVM-025 evaluation board. The output is set to 5 V  and the input supply is 3.3V
When applying a load transient from 100 mA to 1 A using a DC electronic load in pulse mode, the output voltage drops (Nearly 3V)significantly and does not maintain regulation.
