Hello everyone.

I am currently working in GPRS based sollution and i am planning to use an LM2596.

These are the parameters:

Vin: 40V

Vout: 5V

The measured current of the circuit is 700mA (with GPRS transmitting and receiving)

I know the GPRS module have 2A burst. Should I choose the external components with that burst in mind or should I choose them according my current needs?

Which other regulator would you reccomend for this design?

Thanks,

Javier.

Hi Javier,

You can also use the LM46002 for the application
www.ti.com/.../lm46002

It is a synchronous buck with internal compensation

Thanks

Hello Ariel thanks for your answer.

I will check the LM46002.

Please let me know when you have information regarding the current value to be considered.

Thanks again for your help,

Javier.
