Part Number: LM3481EVAL Other Parts Discussed in Thread: TIDA-01592 Hello,
On the schematic of the TIDA-01592 reference design, there are red cross on top of R1 and R7; yet in Figure 15 on page 21 of the Design Guide: TIDUDS2.PDF, R1 and R7 were populated…

Hello,
On Page 11 of the Reference Design Guide, TIDA-0159, a red cross is on R30 and R36, does the red cross mean no fit or 0 ohm, as on Figure…
Hi Mark,
Thanks for using the e2e forum. A red cross in the schematic means the component is not populated. By removing R30 and R36, you 'disable' the snubber circuit. This increases efficiency, but also increases potential switch node overshoots and…
Hi Tom,
Thank you for your interest in Ti's Power products.
Using wires on a perforated board is not going to work. It's essential to use a proven board layout to validate this type of design. May I suggest you order an EVM from the following link…
Other Parts Discussed in Thread: LM3481EVAL , LM3481 Hi,
I've designed a TINA TI schematic for a DC/DC step-up converter based on the LM3481. Basically, it is the LM3481EVAL board with just a few minor changes.
I just can't get it working properly…
Other Parts Discussed in Thread: LM3481EVAL TI Team,
I have two requests. First, can I get the design files (gerber files) for the LM3481EVAL board? http://www.ti.com/lit/ug/snva304/snva304.pdf
Second, with the proposed layout on the evaluation board…
Hi Tommy,
thank you for your quick respond.
OK, I got Cin.
Concerning Rsen (and also Rsl) I still have some unclarities left.
The formula to verify stability on p. 16 says in the denominator [ Vo - (2xVin) ]. Given that my output voltage is 12…
Hello Jamaal, Eric and Todd,
The softstart circuit is just helping to reduce the inrush current. It would not help with the latch on of the FET at lower inputs. You really need UVLO for that. I have attached another small simple schematic which shows…
