Figure 8: Thermal plot of converter at 55 amp load current with 55°C air flowing at the rate of 200 LFM. Air is flowing across the converter from output to input (nominal input voltage). Figure 9: Turn-on transient at full load (resistive load) (10 ms/div). Input voltage pre-applied. Top Trace: Vout (1V/div). Bottom Trace: ON/OFF input (5V/div) Figure 10: Turn-on transient at zero load (10 ms/div). Top Trace: Vout (1V/div). Bottom Trace: ON/OFF input (5V/div). Figure 11: Output voltage response to step-change in load current (50%-75%- 50% of Iout(max); dI/dt = 0.1A/µs). Load cap: 15µF, 450 m Ω ESR tantalum cap and 1µF ceramic cap. Top trace: Vout (100mV/div), Bottom trace: Iout (20A/div). Figure 12: Output voltage response to step-change in load current (50%-75%- 50% of Iout(max): dI/dt = 5A/µs). Load cap: 480µF, 15 m Ω ESR tantalum cap and 1µF ceramic cap. Top trace: Vout (200mV/div), Bottom trace: Iout (20A/div). |
