Step Down Voltage Regulator with Reset TLE 6365 Features Step down converter Supply Over- and Under-Voltage-Lockout Low Output voltage tolerance Output Overvoltage Lockout Output Under-Voltage-Reset with delay P/PG-DSO-8-3, -6, -7, -8, -9 Overtemperature Shutdown Wide Ambient operation range -40 C to 125 C Wide Supply voltage operation range Very low current consumption Very small PG-DSO-8 SMD package Green Product (RoHS compliant) AEC Qualified Functional Description The TLE 6365 G is a power supply circuit especially designed for automotive applications. The device is based on Infineons power technology SPT which allows bipolar and 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.
