Austin Series Non-Isolated SMT DC - DC Power Modules:
Efficiency
Figures 53 61 show typical efficiency charts for Aus-
tin Power Modules at different input voltages. The data
reflects a 25 °C ambient temperature. Efficiencies will
decrease approximately 2% at maximum tempera-
tures. Efficiency is measured in production at 25 °C
and full load.
Figure 53. Efficiency: 3.3 VIN, 1.5 VOUT
Figure 54. Efficiency: 3.3 VIN, 1.8 VOUT
Figure 55. Efficiency: 3.3 VIN, 2.0 VOUT
Figure 56. Efficiency: 3.3 VIN, 2.5 VOUT
Figure 57. Efficiency: 5.0 VIN, 1.5 VOUT
