Efficiency vs. Output Current Figure 2. Voltage Ripple vs. Output Current Figure 3. Power Dissipation vs. Output Current Figure 4. VOUT= 1.8 V, IOUT= 10 A, COUT1= 200 µF ceramic, fSW= 500 kHz Figure 5. Safe Operating Area Figure 6. 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 1, Figure 2, and Figure 3. (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 2 oz. copper. Applies to Figure 5 and Figure 6. 8 Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated Product Folder Links: TPS84A20 |
