LP87524-Q1: maximum output current of one single phase

ke zhou
Prodigy 10 points
Part Number: LP87524-Q1

Hello,

I am now trying to use a LP87524 q1 DC DC converter to convert a voltage from 5V into 3.3V, 2.7V, 1.8V and 1.2V. And because 4 different output voltages are needed, I will choose the configuration of four 1-phase outputs.

But now I have a problem, the current of the load that I intend to connect after the 1.2V output is pretty big, about 3A. I want to ask if this output can bear a current of 3A, what is the maximum current output of one single phase in the four 1-phase configuration?

In the datasheet it's actually written that when input voltage is bigger than 3V, then the maximum output current of a single phase in 1-phase configuration is 4A, but the output voltage is not really specified in this term. I actually want know, when the output voltage is fixed as 1.2V, what is the maximum current output then?

thanks a lot in advance!

Best regards

Max

    Hello Max,

    There are several different OTP spins of this product family and each has different current limits for the bucks. You can see the current limits for the particular part number you are using in the Technical Reference Manuals which are available on the product folder in ti.com. 

    Thanks.

    Regards,
