7.3.3 Optimized Transient Performance from PWM to PSM Operation
For most converters, the load transient response in PWM mode is improved compared to PSM, because the converter reacts faster on the load step and actively sinks energy on the load release. As an additional feature, the TPSM8286xA automatically stays in PWM mode for 128 cycles after a heavy load release to bring the output voltage back to the regulation level faster. After these 128 cycles of PWM mode, it automatically returns to PSM (if VSET/MODE is low). See Figure 7-1. Without this optimization, the output voltage overshoot is higher.
