SDAA017 July 2025 TPS62810
A practical approach to achieving better load transient performance and higher efficiency is proposed in this application note. As the design has been confirmed with the actual application case in SSD, the design operates properly and delivers improved performance in terms of load transient response and efficiency compared to using a fixed mode (either Auto Mode or FPWM). The key point is that the SSD controller receives a signal from the host prior to any actual system load transition between light and heavy load states, which can be utilized to trigger a mode change in the TPS62810 using the MODE or SYNC pin. The signal from the SSD controller helps achieve design targets outlined in this document, and this makes the design an excellent choice.
