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 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…
