Part Number: TPS62160EVM-627

Dear,

our client test TPS62160EVM-627, and we operating condition:

VIN:6V

    The waveform you are highlighting from TI literature is a continuous conduction waveform.

    The waveform you are highlighting from lab data looks to be discontinuous conduction mode waveform. This can be determined by waveform signature and load current setting for the data.

    See comparison below.
