PWM operation. All of the following curves were plotted at TJ = +120°C. For the test conditions, see Table 1.

Figure 27. VIN = 3.3V, VOUT = 0.8V, fSW = 900kHz

Figure 28. VIN = 3.3V, VOUT = 0.9V, fSW =1MHz

Operating condition: TA = +25°C, no air flow. Typical values are used unless otherwise noted. (Cont.)
