4.1 Load Transient Test for TPS61299 and TPS61099

Figure 4-1 shows the load transient waveform of TPS61299 application with fast transient mode from 0 A to 0.5 A when VIN = 3.6 V, VOUT = 5 V. Figure 4-2 shows the load transient waveform of TPS61099 from 0 A to 0.5 A when VIN = 3.6 V, VOUT = 5 V. The ttran of TPS61299 application with fast transient mode and ttran of TPS61099 is 8us, 86.8us separately.
