TLE7368EXUMA1 Description

The TLE7368EXUMA1 is a multifunctional power supply circuit especially designed for Automotive powertrain systems using a standard 12 V battery. The TLE7368EXUMA1 is intended to supply and monitor next-generation 32-bit microcontroller families (13 μm lithography) where voltage levels such as 5 V, 3.3 V, or 1.5 V are required. The regulator follows the concept of its predecessor TLE6368/SONIC, where the output of a pre-regulator feeds the inputs of the micro's linear supplies. In detail, the TLE7368EXUMA1 cascades a Buck converter with linear regulators and voltage followers to achieve the lowest power dissipation. This configuration allows the power of the application even at high ambient temperatures.
