TLE6368G2AUMA1

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 device 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 TLE6368-G2 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.

• High efficiency regulator system
• Stand-by mode with low current consumption
• Suitable for standard 12V/24V and 42V PowerNets
• Step down converter as pre-regulator 5.5V/1.5A
• Step down slope control for lowest EME
• Switching loss minimization
• Six independent voltage trackers (followers) 5V/17mA each
• Stand-by regulator with 1mA current capability
• Three independent undervoltage detection circuits for each linear post-regulator
• Power on reset functionality
• Tracker control and diagnosis by SPI
• All outputs protected against short-circuit
