Product Overview
TLE7368E is an Infineon Technologies automotive multifunction power-supply IC that combines a buck stage with post-regulators and tracking regulators. Its confirmed operating input range is 4.5 V to 45 V, and the exact manufacturer package is PG-DSO-36.
This architecture matters more than a single output-voltage headline: the device manages multiple regulated rails and also includes a window watchdog. Those functions should be checked as a system-level power-management combination when evaluating compatibility.

Power-Architecture and Procurement Notes
The 4.5 V to 45 V input range defines the supported supply envelope and should be matched to the actual system rail, not to an absolute-maximum assumption. The combination of a buck regulator, post-regulators and tracking outputs means that a substitute must reproduce the required multi-rail architecture rather than simply provide one matching voltage.
The window watchdog is another integration constraint because it adds a supervision function beyond voltage regulation. Its presence can affect both schematic connectivity and system-control behavior.
Infineon identifies the active orderable implementation in PG-DSO-36. The local distributor-style package description BSSOP-36-EP-300mil should therefore not override the manufacturer’s package identity when footprint and sourcing data are checked.
Within Infineon’s TLE7368 automotive multi-output PMIC family in the same PG-DSO-36 package, compare TLE7368-3E when the external-NPN LDO3 core rail must be 1.3 V ±2% rather than this TLE7368E’s 1.5 V ±2%. Infineon documents LDO3 output voltage as the functional difference among TLE7368E / TLE7368-2E / TLE7368-3E.
