Next Generation Micro Controller Supply

The TLE7368 device is a multifunctional power supply circuit especially designed for Automotive powertrain systems using a standard 12 V battery. The device 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 TLE7368 cascades a Buck converter with linear Regulators and voltage followers to achieve lowest power dissipation. This configuration allows to power the application even at high ambient temperatures. By Infineon Technologies Corporation
