Efficiency vs. Output Current Figure 16. Voltage Ripple vs. Output Current Figure 17. Power Dissipation vs. Output Current Figure 18. Safe Operating Area Figure 19. Safe Operating Area Figure 20. Safe Operating Area (1) The electrical characteristic data has been developed from actual products tested at 25°C. This data is considered typical for the converter. Applies to Figure 15, Figure 16, and Figure 17. (2) At light load the output voltage ripple may increase due to pulse skipping. See Light-Load Behavior for more information. Applies to Figure 16. (3) The temperature derating curves represent the conditions at which internal components are at or below the manufacturer's maximum operating temperatures. Derating limits apply to devices soldered directly to a 100 mm × 100 mm, 4-layer, double-sided PCB with 1 oz. copper. Applies to Figure 18, Figure 19, and Figure 20.
