Part Number: TPS5432EVM-116

Dear sir,

I'm checking the EVM.

I set Vin=3.5V, Vout=3.3V/ 10ohm load, but the vout have 0.5Vpp ripple noise.

Does it support the Duty=100%?

I attache 2 measured wavedorms.

1: Vin=3.5V, Vout=3.3V load=10ohm

2: Vin=3.7V, Vout=3.3V load=10ohm

Hi Gordon,

As explained in the datasheet, the device can work in 100% mode as long as the design requirements mentioned in the datasheet is followed. But, do not operate the device at 100% duty ratio with no load. Please read the datasheet for a better understanding.

Regards,
