Part Number: LM25148-Q1 Tool/software: Hi BU team
My customer need to check if LM25148-Q1 support below protections and pls share your comments.
1. Support the output overvoltage protection similar with MPQ2918.
2. After the pre-regulator with…
Part Number: LM25148-Q1 Hi team,
May I ask what the maximum current output capability of the LM25148-Q1 is? With a 12V input and 5V output, can it continuously output 20A(100W load)? If it can, please provide the relevant test waveforms. If not, please…
Part Number: LM25148-Q1 Other Parts Discussed in Thread: LM25148 Tool/software: Hello, everyone,
When I used LM25148, there was a problem of no output of 2pcs SW, and one IC suffered serious ablation.
The current bypass voltage is set to 12V. The…
Part Number: LM25148-Q1 Tool/software: Hi expert,
I want to know how to calculate the PFM/PWM transition point in PFM(diode emulation) mode. What's the meaning for PFM detection threshold?
Thanks!
Part Number: LM25148-Q1 Hello,
The datasheets hints to this but doesnt explicitly confirm so I need to double check:
When this device regulates at light loads (less than 5mA in this case) it still operates in DCM when PFM is enabled correct?
Thanks…
Part Number: LM25148-Q1 Other Parts Discussed in Thread: LM25148 Tool/software: Hi team,
Customer RD is facing the wrong calculation result on LM25148. Per actually test on system, they found it should be using minimum value to calculate the required…
Part Number: LM25148-Q1 Tool/software:
I designed a Buck converter with the LM25148-Q1 using the Powerbench designer (schematic attached). This is supposed to be rated for 15A according to the designer, However even at 5A the voltage drops. Below…
Part Number: LM25148-Q1 Tool/software: Hi Team,
We have some discussion in this internal thread before, while customer's engineer want to directly have some further discussion here.
