Part Number: LM61460EVM Hi Team,
Could LM61460EV M-FS-400K operate at sw=2.1MHz?
I modified the RT resistance but it didn't change the sw frequency. (maintain 400k HZ SW frequency)
Is this IC switching frequency fix at 400kHz?

Part Number: LMQ61460 Other Parts Discussed in Thread: LM61460 , , LM61460EVM Hello team,
I have question about input capacitors. In my understanding, LMQ61460 has internal 22nF bypass cap at the each input pin, but LM61460 does not.
I just looked at LM61460EVM…
Hello,
The efficiency curve for the AUTO mode device should have been on the LM61460EVM-AS-400K evaluation kit which is using the LM61460AASQRJRRQ1 IC.
How is your efficiency bench connected? In the case where you are measuring efficiency at this light of…
Hi,
In order to better solve the problem, please provide the circuit schematic diagram. Also, may I ask if this phenomenon occurred in the test on the LM61460EVM? Or on the customer's own board? Looking forward to your reply. Thanks.

you could you apply a TI official EVM online, www.ti.com/.../LM61460EVM
and if you purpose check the boundary ,or want to use function well, suggest to set a reasonable EN voltage away from the edge of H/L .leave a little buffer.
if you defined it as a…
Hi,
From your original comment " Note that VMAIN outputs 5V in both cases as configured.", does this mean you had tested both boards (Case A and Case B) and observed that both are regulating 5V output properly?
Resistance between VOUT/GND will…
Hi Roy,
Instead of calculations, the best way to go about evaluating is by testing on the EVM.
I would suggest taking the existing LM61460EVM and configure it for 3.3Vout.
Then scaling and progressively loading the device with current from 0A to 3.5A…
Part Number: LM61460 Hi team,
My customer measured Vout ripple on LM61460EVM-AS-400K. Could you check and comment for each condition 1 and 2? I'd like to know that these waveforms are normal or not.
Condition.1
Vin=24V
Vout=3.308V (Rfbt=300kohm, Rfbb…
Hi Eric,
Please use the land pattern in the datasheet for reference on the LM61460 footprint.
Also available in the product folder is the EVM design file for the LM61460EVM that customers can use as reference when creating their new layout.
