Figure 8: Thermal plot of converter at 4.2 amp load current (50W) with 55°C air flowing at the rate of 200 LFM. Air is flowing across the con- verter from input to output (nominal input voltage). Figure 9: Turn-on transient at full load (resistive load) (10 ms/div). Input voltage pre-applied. Ch 1: Vout (5V/div); Ch 2: ON/OFF input (5V/div) Figure 10: Turn-on transient at zero load (10 ms/div). Ch 1: Vout (5V/div) Ch 2: 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: 10µF, 100 m Ω ESR tantalum capacitor and 1µF ceramic capacitor. Ch 1: Vout (200mV/div), Ch 2: Iout (1A/div). Figure 12: Output voltage response to step-change in load current (50%-75%- 50% of Iout(max): dI/dt = 5A/µs). Load cap: 470µF, 30 m Ω ESR tantalum capacitor and 1µF ceramic cap. Ch 1: Vout (200mV/div), Ch 2: Iout (1A/div). Semiconductor junction temperature is within 1°C of surface temperature |
