ZHCSQY3 march 2023 TPS546D24S
PRODUCTION DATA
The TPS546D24S can be programmed as a standalone device (Single Output, Single Phase) loop controller device of a single-output multi-phase stack of devices, or a loop follower device to a loop controller of a mult-phase stack. The details of the recommended pin connects for each configuration is given in Table 7-5.
