Step 8 Voltage sequencing & tracking
Sequencing
Many of the common power supply sequencing methods can be implemented using the SS/TRK, ENABLE and PG pins. The
sequential voltage tracking is illustrated below using two devices. The PG pin of the first device is connected to the ENABLE
pin of the second device which enables the second power supply once the primary supply reaches regulation. Both modules
can apply different slopes of the output voltage during start by selecting the individual soft-start capacitors accordingly.
