lm2621 2V to 6V

Other Parts Discussed in Thread: LM2621

I'm interested in using the LM2621 on a project I'm designing.

I need to step up a voltage from around 1.2-3V to a steady 6V (the battery input can vary). Would the LM2621 be capable of making such a conversion?

I have read the datasheet of LM2621,but all of the output voltage is 5v in the application circuit, Can you show me a application circuit that can step up 2V to a steady 6V.

Thanks for your help!

Andy,

As long as your output current does not exceed 1A, the LM2621 can be designed to output 6V.

Please use WEBENCH on the right side of the product page.

It will help to design design the circuit and calculate the proper components for your application.

Please let me know if you have any further questions.

Andy, Richard,

I am closing this post because there is a duplicate with the same question by Andy. I have answered that one and suggested use of a different part because of the duty cycle limitations on the LM2621.

Regards,
Akshay

Hello Richard,

thanks for your reply.

I have used the WEBENCH,but it do not give me any circuit.So can you give me the ciruit ?

best wishes

regards,

Andy
