Part Number: LM25575 Other Parts Discussed in Thread: LM27762 , ADS114S08 , LM27762EVM Hi,
This is regarding the LM25575MHX/NOPB Step down switching regulator. Refer attached schematic snapshot and Power supply topology.
We are using this in one of…
Part Number: LM25575 Hello team,
I received a question from the customer.
I designed a buck-boost converter using Webench, is it OK to connect the VCC pin to -12V, I am aware that the VCC pin is an internal power supply made from VIN, is this a problem…
Part Number: LM25575 Hello, My customer has a question for the blew circuit in the datasheet.
1) For pin 10(SS), 1.25V seems to be output on this pin from the block diagram. Is it correct? I believe that 1.25V is just a typ value. Could you tell…
Part Number: LM25575 I am looking to get some more information about the thermal metrics on PN: LM25575
I found another component (LM63610) that has the same case (HTSSOP) and included some additional thermal metrics in the datasheet. Right now I am…
Part Number: LM25575-Q1 Hi Expert,
Our customer would like to configurate LM25575-Q1 to inverting buck-boost topology. They would like to know how to deal with Exposed Pad properly. Is it connected to GND internally? Thanks.
BR,

Other Parts Discussed in Thread: LM25575 Hi,
According to the datasheet of LM25575, as you can seen in Figure 3, there is about 500 ns delay between CLK signal and the switching on the SW which in practice, I could verify that. My question is that…
Other Parts Discussed in Thread: LM25575 Hi, My customer has question about LM25575. Could you tell us about question?
Q: Is Power pad direct connected to AGND and PGND in internally ?

Other Parts Discussed in Thread: LM25575 , LM43603 Hi,
This is Ben. I want to discuss some function block about LM25575 with you.
1. When I connect two LM25575 by SYNC pin. Can they become a muti-phase power source?
2. In my opinion, because of…
Other Parts Discussed in Thread: LM25575 Hello!
I have a LM25575 hooked up as an inverting power supply, giving me -12V out of +12V. I followed the Webbench Design closely and ordered the parts it recommended me (except for resistors). I attached the…
Other Parts Discussed in Thread: LM25575 , TPS54540 Hi,
I have a TPS 54540 to generate +15 VDC from 28VDC and in the cascaded structure, I have used LM 25575 to generate -15 VDC from +15 VDC. I do like to synchronize both power module to an external…
