Features
Functional Description
The TLE 6365 G is a power supply circuit especially designed for automotive
applications.
The device is based on Infineon’s power technology SPT
CMOS control circuitry to be integrated with DMOS power devices on the same
monolithic circuitry.
The TLE 6365 G contains a buck converter and a power on reset feature to start up the
system
The very small PG-DSO-8 SMD package meets the application requirements.
It delivers a precise 5 V fully short circuit protected output voltage.
Furthermore, the build-in features like under- and overvoltage lockout for supply- and
output-voltage and the overtemperature shutdown feature increase the reliability of the
TLE 6365 G supply system.
