When I was testing TPS63070, the input voltage was 4.6V~5.2V. When starting with load, the voltage could not output 5V. It can output 5V2A when the load is connected after it is started. Why does this problem occur? Does the TPS63070 fail to start under heavy load? If so, what is the recommended chip? I want 4.5~5.2V to 5V@2A.
