Part Number: LM25149
Hi, I am working on a design involving TI's LM25149 buck regulator IC to convert a 12V input voltage (5-14V range) down to 3.8V with a peak current of 3.5A. Average load current is 1A but short bursts up to 3.2A are expected. The…
Part Number: LM25149-Q1 Hello.
Trying to design a power supply in two versions using the LM25149-Q1, with the same input voltage range of 15V to 36V. One version is for a 7.5V / 12A output, and the other is for a 12V / 10A output.
For some reason…
Part Number: LM25149 Hi sir,
Customer using EVM and wants to adjsut the Vout, so change the RFB2 from 19.1K-> 3.48K.
In the result, EVM can't power up. (Originally okay)
After changing back the RFB2 to originally board setting, EVM can't power…
Part Number: LM25149-Q1 Hi TI
Description We are experiencing an issue where our newly developed board using the LM25149-Q1 in a dual-phase interleaved configuration exhibits a 5V output runaway during light-load startup at 70℃ high temperature under…
Part Number: LM25149 Tool/software: HI Ti Team:
I have two questions, please help to answer,thanks.
1.The reference design of resistance R6942 uses 0.24R, but we can use 1R here,Is that OK?
2.Whether the interior of PIN23 is connected to GND?
Part Number: LM25149 Tool/software: We modified the LM25149-Q1 EVM to 12v output voltage
Modified items: connect VCCX to GND, FB to 49.9K to VDDA
Test conditions: Input voltage 24V, output 12V, connect load machine (1A, 3A, 5A) to verify conversion…
