Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Part Number: LM5148 Tool/software: Hello,
I implement LM5148 buck for two power supplies: +24V to +5V and +24V to +15V on same board, and on sequence +5V, then +15V. They both have +5V connected to VCCX.
Unfortunately, the +15V keeps failing. It does…
Part Number: LM5148 Other Parts Discussed in Thread: LM25148 Tool/software: Hi TI
The datasheet of LM5148 table 9.1 shown the common formula to maeuserd MOSFET'S power loss
But the spreadsheet of "LM5148_LM25148_quickstart_calculator_A4" didnt u…
Hello Christian,
You can use a single LM5148 for 12A output current.
please see evaluation board linked below.

Part Number: LM5148 Other Parts Discussed in Thread: LM5149 Tool/software: hi
Can LM5148 support pre-bias start up in which the Vout powers up first than Vin?
Part Number: LM5148 Tool/software: Is it possible to use the FB pin to control the output voltage in real time? We are thinking of using a microcontroller D/A output connected to the FB pin in order to adjust the output voltage to +/- 1.0 volts of the…
Part Number: LM5148 Tool/software: Is it possible to get the unencrypted PSpice models for the LM5148 or similar parts? We are working on our Senior Design Project and would like to use this part for our PMIC and need to simulate it to see if it works…
Thank you, Tim for the suggestion. I ordered the ones that were listed on the LM5148 eval design. They are expected to arrive today. Will keep you posted.
