Part Number: LM5148 Hey everyone, I'm bumping up against a bit of ringing at the high-side gate of a LM5148 60V->12V Buck controller and I'm hoping someone out there has seen this before. I'm assuming I made a naive mistake somewhere, but here we go.…
Part Number: LM5148 Dear TI Engineer,
We have designed with LM5148 to achieve a 48V input and 30V/10A output. We designed the following circuit based on LM5148_quickstart_calculator tool, but found no output during testing. Can you help check is there…
Part Number: LM5148 Other Parts Discussed in Thread: LM5149-Q1 , Hi all,
I am looking to run simulations of the LM5148-Q1 in LTSpice. I saw on previous forum posts that there is an available model of the LM5149-Q1 but that the unencrypted model that…

Hi,
I already have a design with LM5148, with an output of 21V and 15A. As it is now this load is pulsed with a 10ms on time and 50% duty cycle.
I would like…
Part Number: LM5148 Hello TI Support,
We are having an issue with current sharing in our LM5148 dual-phase buck converter design. The primary phase carries significantly more current than the secondary phase and heats up considerably more.
I took…
Part Number: LM5148 Other Parts Discussed in Thread: LM5137 Hi Team,
As we are planning to design programable variable power supply with LM5148 (Buck topology),
our power supply specs are as below
Input Voltage: 48Vdc
Output voltage: 1V to 24V…
Part Number: LM5148 Other Parts Discussed in Thread: LM654A5-Q1 , CSD18511Q5A Hello,
I'm working on a buck converter (input 20 Vac 50 Hz, output 6.3V 12 A). Here is its schematic:

Part Number: LM5148 Hi Team,
My customer is using the LM5148 (48V to 12V) under light load (less than 0.5A). The output ripple is between 13.16V and 13.63V, so I think this might be causing the PGOOD drop. But according to the datasheet, there's a 25…
Part Number: LM5148 Other Parts Discussed in Thread: LM25148 Hi Team,
Using LM5148RGYR, At present, the ripple is tested in the laboratory. The input voltage is+24V, the output voltage is 5.2V/4A, and the inductance is 3.3uH. However, during the actual…
