The TPS65653-Q1 device supports start-up and shutdown sequencing with programmable delays for different regulator outputs using single EN control signal. The Buck regulator is selected for delayed control with:
The GPO (and GPO2) digital output signals can be also controlled as a part of start-up and shutdown sequencing with the following settings:
An example of the start-up and shutdown sequences for the buck regulators are shown in Figure 10. The start-up and shutdown delays for the Buck0 regulator are 1 ms and 4 ms; for the Buck1 regulator start-up and shutdown delays are 3 ms and 1 ms. The delay settings are used only for enable/disable control with EN signal.
