I - Output Current - A Figure 2-1. TPS54332EVM-416 Efficiency Figure 2-2 shows the efficiency for the TPS54332EVM-416 at lower output currents between 0.025 A and 0.250 A at an ambient temperature of 25°C. SLVU276A – FEBRUARY 2009 – REVISED OCTOBER 2021... -
Page 6: Output Voltage Load Regulation
The efficiency may be lower at higher ambient temperatures, due to temperature variation in the drain-to-source resistance of the internal MOSFET. 2.3 Output Voltage Load Regulation The load regulation for the TPS54332EVM-416 is shown in Figure 2-3. V = 15 V... -
