TPSM828512: SW waveform at heavy load current

Part Number: TPSM828512

Tool/software:

Hi support team,
The SW waveform of the TPSM828512EVM was checked under the following conditions.

Vin = 5V
Vout = 1.8V
Mode = FPWM

With no load, the High width is constant at 160ns.

When the load current is increased to 1.5A, the High width alternates between 140ns and 200ns.


Why does the High width not become constant when the load current is increased?

Regards,
