LMQ61460-Q1: LMQ61460-Q1

Part Number: LMQ61460-Q1

When I make a design in WebEnch using LMQ61460AASQRJRRQ1, can I replace it with LMQ61460AFSQRJRRQ1 without changing schematics?

Thanks for help,

Hi Jean,

Yes, no need to change the circuit for this replacement, but the light load eff will drop if FWPM version is used.

Hi Andy

follow this forum, customer reply:

Our schematics is nearly the same as the LMQ61460-Q1 EVM-Modul (with LMQ61460AFSQRJRRQ1). Without load output-voltage is 5.1 Volt. Wenn we increase the load Output-voltage dorps. What could be the problem?

Hi Aosker,

You can check the voltage on the Vout sensing point of top feedback resistor, if voltage on this point is stable, then problem is caused by improper output sensing or too high trace resistance between Cout and load point.
