Product Summary

The TLE6368G1 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 TLE6368G1 is intended to supply 32 bit micro-controller systems which require different supply voltage rails such as 5V, 3.3V and 2.6V. The regulators for external sensors are also provided. The TLE6368G1 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. The step-down converter delivers a pre-regulated voltage of 5.5V with a minimum current capability of 1.5A. Supplied by this step down converter three low drop linear post-regulators offer 5V, 3.3V, or 2.6V of output voltages depending on the configuration of the device with current capabilities of 800mA, 500mA and 350mA.
