TYPICAL CHARACTERISTICS (PVIN = VIN = 5 V) (1) (2)
Figure 7. Efficiency vs. Output Current
Figure 8. Voltage Ripple vs. Output Current
Figure 9. Power Dissipation vs. Output Current
Figure 10. Safe Operating Area
Figure 11. VOUT= 1.8 V, IOUT= 7 A, COUT= 200 µF ceramic, fSW= 500 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 7, Figure 8, and Figure 9.
(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, 4-layer PCB with 2 oz. copper.
Applies to Figure 10.
