TPS568215: Inquiries about TPS568215RNNR

Part Number: TPS568215

Hello,

My customer is using the TPS568215RNNR with VIN=13V and VOUT=1.509V.

They have some questions about the device.

Q1) Is there a shutdown function according to input voltage changes? If so, what is the input voltage for shutdown under the above user conditions?

Q2) What is the current in the internal diode?

Q3) How many voltage output modes can the user select from this device?

Thank you.

JH

    Hi JH,

    1. As long as input voltage is in the range 4.5V-17V. Vin won't shutdown. Vin=13V, Vout=1.509V, No Vin shutdown.

    2. What do you mean the current in the internal diode? What is internal diode?

    3. Please refer to table 5 in the datasheet for inductor/output capacitor/switching frequency selection. Then based on table3 to select MODE pin setting.

    Hope this helps,

    Thanks,

    Nancy
