Part Number: LM25149-Q1EVM-2100 Other Parts Discussed in Thread: LM25149 , We want to design a 12V->5V circuits that is very efficient from 5mA to 4A. We also want the output to maintain regulation as the input drops down to 5.85V. I looked at the LM25149…
Part Number: LM25149-Q1EVM-2100 Other Parts Discussed in Thread: LM25149-Q1 Hi Team,
1. Do you have a reference schematic with dual-phase operation?
2. How to build a dual-phase board by modifying 2 LM25149-Q1 EVMs?
Part Number: LM25149-Q1EVM-2100 Other Parts Discussed in Thread: LM25149-Q1 Hello Team,
Our customer want to evaluate dual phase operation by using 2pcs of LM25149-Q1 EVM but somehow they can't work well.
Can you please let me know the setup to perform…
Part Number: LM25149-Q1EVM-2100 Hi, team
when start up with heavy load(13A), see overshoot on Iout. Is it normal? and what can cause this overshoot? (such as test method?)
test condition: Vin=12V Vout=3.3V Iload=13A
Part Number: LM25149-Q1EVM-2100 Hi support team:
when system output 3.3V/1A, I tested output ripple is 280mv(output capacitor is 188uF ) in PFM mode.
I think this voltage ripple is too large, could you please tell me what is the ideal voltage ripple in this…
Part Number: LM5143-Q1EVM-2100 Other Parts Discussed in Thread: LM5143 Hello,
Could you advise how EN1/2 is only 1.2V even when VIN is applied with 12V in LM5143EVM?
I measure VIN and PGND, then see 12V. I measure EN1 and PGND, then see 1.2V. EVM used…
Part Number: LM5143-Q1EVM-2100 Other Parts Discussed in Thread: LM5143 Hi team,
In our LM5143EVM,there is a start-up characteristic showing as following:
With the Css=68nF setup, the calculated soft start time should be 1.94ms, but I am little confusing…
