Efficiency vs. Output Current Figure 22. Voltage Ripple vs. Output Current Figure 23. Power Dissipation vs. Output Current Figure 24. Safe Operating Area Figure 25. Safe Operating Area Figure 26. 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 21, Figure 22, and Figure 23. (2) At light load the output voltage ripple may increase due to pulse skipping. See for more information. Applies to Figure 22. (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 24, Figure 25, and Figure 26. 10 Submit Documentation Feedback Copyright © 2012–2013, Texas Instruments Incorporated Product Folder Links: TPS84259 |
