Product Summary

The TLE6368G2 is a multi voltage power supply system especially designed for automotive applications using a standard 12V / 24V battery as well as the new 42V powernet. The TLE6368G2 is intended to supply 32 bit microcontroller systems which require different supply voltage rails such as 5V, 3.3V and 2.6V. The regulators for external sensors are also provided. The TLE6368G2 cascades a Buck converter block with a linear regulator and tracker block on a single chip to achieve lowest power dissipation thus being able to power the application even at very high ambient temperatures.
