Other Parts Discussed in Thread: TPS61022
Hi,
I am testing with the TPS61022EVM in preperation of using the TPS61022 in a design.
I am testing ultra low power mode and I am seeing efficiencies in the low 80% instead of the 90%.
I am using a power supply to supply Vin and a constant current load of 5mA. My results are below. I expected to see higher efficiencies. Are there things I need to do to improve the efficiencies at low power mode?
Vin | Cin (mA) | Vout | Cout* (mA) | Eff (%) |
4.2 | 7.22 | 5.188 | 5 | 0.855428 |
3.7 | 8.31 | 5.188 | 5 | 0.84366 |
3.2 | 9.64 | 5.19 | 5 | 0.841221 |
3 | 10.4 | 5.189 | 5 | 0.831571 |
2.5 | 12.68 | 5.185 | 5 | 0.817823 |
2 | 16.3 | 5.182 | 5 | 0.794785 |
Thanks
