SLVUA33A March 2014 – July 2021 TPS563900
Figure 2-1 and Figure 2-2 show the efficiency for the TPS563900EVM-574 in CCM at an ambient temperature of 25°C.
Figure 2-3 and Figure 2-4 show the efficiency for the TPS563900EVM-574 in CCM using a semi-log scale to more easily show efficiency at lower output currents. The ambient temperature is 25°C.
Figure 2-5 and Figure 2-6 show the efficiency for the TPS563900EVM-574 in SKIP mode at an ambient temperature of 25°C.
Figure 2-7 and Figure 2-8 show the efficiency for the TPS563900EVM-574 in SKIP mode using a semi-log scale to more easily show efficiency at lower output currents. The ambient temperature is 25°C.
The efficiency may be lower at higher ambient temperatures, due to temperature variation in the drain-to-source resistance of the internal MOSFET.
