Hi Team,
just want to check if there is data or curve on Frequency vs load @ Iout<0.2A, Vout=2.8V.
datasheet only show curve @ Iout>0.2A. Thanks.

Hello Given,
The switching frequency and load current characteristics shown below are performed by using the TLV62084EVM (TLV62084AEVM-828 Evaluation Module) by the following conditions.
Input Voltage = 5 V
Output Voltage = 2.8 V
Load Current = 0.05 A to 0.2 A
Below 0.15A load current the device enters discontinuous conduction mode. Please refer the below waveform with the Vin=5V, Vout=2.8V and Iout= 0.05A.
Yellow= SW node voltage
Cyan= Inductor current
Basically, TPS62084 operates in DCS control with a nominal switching frequency of 2 MHz. In DCS control the switching frequency may vary due to many factors such as circuit losses, propagation delays and tolerance of the passive components. It depends upon the Inductor you used as well.
I would recommend this document to under the frequency variation in DCS control (Understanding frequency variation in the DCS-Control(TM) topology)
Thank you,
Regards,
Moheddin.
