TPS546D24A: Output Voltage Accuracy

Shinichi Yokota

Part Number: TPS546D24A

Hello,

How can I estimate TPS546D24A's output voltage accuracy V_OUT(ACC) under a condition that is not listed in the 6.5 Electrical Characteristics section of the data sheet? I'd like to have the V_OUT(ACC) value under V_OUT = 3300 mV and -40 °C ≤ T_J ≤ 150 °C, for example.

Best regards,
Shinichi Yokota

Hi Shinichi,

The closest output voltage in the table is 1500mV, which has a tolerance of about 0.67% over 40 °C ≤ T_J ≤ 150 °C.

The device has a 40mV resolution for output voltages from 2.4V to 5.5V.

So, I would expect the Vout accuracy for 3300mV condition to be between 0.67% and 1.2%, but closer to the 0.67% rating.

Let me know if this helps.

Thanks,

Joseph

Joseph,

Thanks and sorry that I remember that I asked exactly the same question and got an answer from your team before.
