Part Number: LM5122-Q1 Other Parts Discussed in Thread: LM25122-Q1 , , LM5122 Hi Expert,
I would like to know the difference LM5122-q1 and LM25122-q1, except Max input voltage and switching frequency. Is it ok for p2p drop in? Thanks.

Part Number: LM25122-Q1 Hello,
May I have a quick question on LM25122-Q1 startup waveform?
1. Why there appears a flat region in VOUT when VOUT=VIN?
2. Can I assume how long it would last?
Thanks,
Hi Dehuan,
Thanks for your help!
You have reviewed their schematic before. They add one mosfet in the feedback circuit. If our EVM is ok, then the root cause should be the mosfet circuit.

Part Number: LM25122-Q1 Other Parts Discussed in Thread: LM5122 Dear team,
Could you please help review the schematic? In addition, do we have the efficiency curve? The customer wants to compute the input current, but we can't compute it without efficiency…
Part Number: LM25122-Q1 Hello E2E,
Good day.
Is the switch current and output current both 20A for LM25122-Q1? I have checked the datasheet but was not able to find these values for the said parameters.
Thank you for the help.
Regards, Carlo
Part Number: LM25122-Q1 Hi~ team.
Based on LM25122-Q1 EVM or TIDA reference design, input current oscillation happen only under low input voltage(<9V).
Input, output voltage, output current is also stable, but input current looks start oscillation…
Part Number: LM25122-Q1 Other Parts Discussed in Thread: TIDA-01610 Hi team,
we would use LM25122-Q1 to power supply Class-D. the audio output power is 80W*2=160W max. voltage is 18V.
we reference to the TIDA-01610. In this TIDA scheamtic, use two LM25122…
Part Number: LM25122-Q1
There was a problem using LM25122-Q1.
Input : typ 12V output : 24V, 2A
However, the customer has a shutdown in output load 1.8A.
Could you review my schematic as attached file.
