LMR33620-Q1: Output Voltage Range of LMR33620-Q1

Asha Chandrashekar

Part Number: LMR33620-Q1

Output Voltage Range is mentioned as 1V to 24V.

VREF is 1V as per Datasheet,

As per above formula , Vout cannot be set to 1V by adjusting external resistors . But as per range ,minimum output voltage mentioned is 1V . Could you please justify.

Thank you!

Hi Asha

You can connect FB to Vo directly.

What is your operate condition? Can you share the Vin range and Io?

Thank you.

Hello Gui,

How do we decide the minimum output voltage that can be designed from this Buck ? If we need Vout for 1.1V then should we have to go for resistor divider?

As an example for now we can consider now Vin as 3.3V and Iout being 2A.

Hi Asha

You may consider devices with lower Vin range if Vin is 3.3V. You can choose device whose Vref is 0.6V.

Thanks
