Hi Sir
We design TPS92510 in 5Vin and Vout set to 3.6V, output current set to 0.24A.
But we find we need increase Vin to 5.4V, then LED can normal work.
1.When Vin = 5.4V, to measure LED Vf = 2.75V.
2.when Vin =5V, to measure LED Vf = 2.39V. Can't be drived.
3.When Vin <5V, the Led vf will decrease depend on Vin.
From spec, the TPS92510 should be work in Vin=5V and Vout 3.6V/0.24A. may our design have something wrong to case this kind issue?
