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 Hi Team,
my customer would like to know what fault conditions are covered by the slaves and monitored via power good in the dual-channel automotive synchronous buck controller evaluation module LM5143-Q1EVM-2100.
Thank you…

I have some questions here.
1. LM25143-Q1 can be designed as spec LM25143-Q1?
2. Since this part number is discrete solution and no EVM. if…
Brandon,
What reference design are you referring to?
Actually the device uses current-mode control, the inductor current is part of the control loop.
The larger AC signal will definitely affect the stability, and could make it more stable.
Ultimately…
Sekar,
Looks like you will need dual-phase for 15A+ and no cooling system.
Consider LM25143 as it is a dual-phase chip.
Check out the EVM: https://www.ti.com/tool/LM5143-Q1EVM-2100
You can configure it for 15A by configuring the EVM for dual-phase.
Hope…
Hello,
I do not have a 0.8V source in my possession. My design is identical to LM25149-Q1EVM-2100, but with components for 440 kHz switching frequency.
The datasheet says tie CNFG to GND to disable AEF. But I am still getting the same EMI results.
Part Number: LM5148 Other Parts Discussed in Thread: LM25149-Q1EVM-2100 , LM5149-Q1 , LM5149-Q1EVM-400 Hello,
I am currently in the process of constructing a buck converter with the following specifications:
Input Voltage: 15-80V
Output Voltage: 12.51V …
