TLE 6365 G Q67006-A9515 P-DSO-8-3

Functional description

General

The TLE 6365 G is a power supply circuit especially designed for automotive
applications.
The device is based on Infineon’s 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 P-DSO-8-3 SMD package meets the application requierements.
It delivers a precise 5V 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.

1.2 Pin Definitions and Functions

TLE 6365

Pin

Symbol Function

No

1R Reference Input; an external resistor from this pin to GND

determines the reference current and so the oscillator / switching
frequency

2RO Reset Output; open drain output from reset comparator with an

internal pull up resistor

3BUCBuck-Converter Compensation Input; output of internal error

amplifier; for loop-compensation and therefore stability connect
an external R-C-series combination to GND.

4GNDGround; analog signal ground

5 V

CC

Output Voltage Input; feedback input (with integrated resistor
devider) and logic supply input; external blocking capacitor
necessary

7BUOBuck Converter Output; source of the integrated power-DMOS

6BDSBuck Driver Supply Input; voltage to drive the buck converter

powerstage

8 V

S

Supply Voltage Input; buck converter input voltage; external
blocking capacitor necessary.
