Figure 12.
(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 9 , Figure 11 and Figure 10 .
(2) Output ripple may increase up to 2x when operating at input voltages greater than (V
O
x 11). See the Smart Sync section of the
datasheet for input voltage and frequency limitations.
(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 modules soldered directly to a 100 mm x 100 mm double-sided PCB with 2 oz. copper.
For surface mount packages (AS and AZ suffix), multiple vias must be utilized. Please refer to the mechanical specification for more
information. Applies to Figure 12 .
