Part Number: LM5177 Other Parts Discussed in Thread: PMP7837 , LM5122 Two LM5177 use the same COMP to make inductor current close.
Use an external voltage follower conntected one COMP pin to overlay the other COMP pin.
Hi Bharath,
Thank you for your interests. However, I am afraid your power level (~400W) is excessive for the TPS43060. I would recommend you to use LM25122 in dual phase or even four phases to deliver such high power. You can take a look at the following…
Hi User,
Two issues here:
(1) The LM5122 requires 4.5V to startup. Webench makes it a requirement to start the design. The 3V in the datasheet means the LM5122 can support Vin=3V once it is started up. So, you should not use 3V as the input condition…
Hi Vijay,
By multi phase I mean several "smaller" boost converters are combined in the fashion of paralleling, namely their input and output are tied together, such that the total power is shared, or split, among these smaller converters. Refer to the…
Please refer to the example at http://www.ti.com/tool/PMP7837
This is for the LM5122 but the same circuit structure can be used for the LM25122-Q1.
There is also an 700W peak power reference design with the LM25122-Q1. The link is at: www.ti.com…
Hi Fajar,
Thank you for your interests in the LM5122. It seems you want 4 phases design. You cannot easily make two independent power supply to share the loads. The two additional phases (namely your secondary PMP7937) must be set to the slave mode…
Hi Roy,
There are several other relevant boost reference designs that could be useful here. You may want to check with your customer if this is a continuous power or peak power rating.
