Description

The TLE7368E is a multifunctional Power Supply Circuit especially designed for automotive powertrain systems using a standard 12V battery. The regulator follows the concept of its predecessor TLE6368, 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. The step-down converter delivers a pre-regulated voltage of 5.5V with a minimum peak current capability of 2.5A. Supplied by this step down converter two low drop linear post-regulators offer 5 and 3.3V (2.6V) with high accuracy. The current capability of the regulators is 800 and 700mA. The 3.3V (2.6V) linear regulator does have its own input allowing to insert a dropper from the Buck output to reduce the on chip power dissipation if necessary.
