Efficiency vs. Output Current Figure 12. Voltage Ripple vs. Output Current Figure 13. Power Dissipation vs. Output Current Figure 14. Safe Operating Area Figure 15. Safe Operating Area Figure 16. VOUT=1.2 V, IOUT=3 A, COUT1=47 µF ceramic, COUT2= 330 µF POSCAP, fSW=480 kHz (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 11, Figure 12, and Figure 13. (2) 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 double-sided PCB with 1 oz. copper. Applies to Figure 14 and Figure 15. 10 Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated Product Folder Links: LMZ31506H |
