TPS62740EVM-186: TPS62740EVM-186

Part Number: TPS62740EVM-186

Greeting,

I am using TPS62740 evaluation module to conduct various tests. I have used the capacitor and resistor values as per the schematics provided by ti. I have noticed that when the the device performs normally from a voltage range of 4.5V to 3.5V. Below that the voltage simply follows the input. I want a output of 3.3V for my project. How can i maintain a constant voltage of 3.3V At 3.5v? Thank you.

    Hi Akash,

    Thanks for using our technology.

    I would like to bring to your attention how much current you are advised to draw from your device under different voltage conditions:

    How much current is your application drawing?

    Additionally, the TPS62740 has a 100% mode, which is automatically activated when the input voltage is close to the output voltage. To understand that more, please refer to section 9.4.2 in the datasheet and to this application note (slyt747).

    Best regards,

    Omar
