Symbol Function

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

3BUC

Buck-Converter Compensation Input; output of internal error

amplifier; for loop-compensation and therefore stability connect

an external R-C-series combination to GND.

4GND

Ground; analog signal ground

5

Output Voltage Input; feedback input (with integrated resistor

devider) and logic supply input; external blocking capacitor

necessary

7BUO

Buck Converter Output; source of the integrated power-DMOS

6BDS

Buck Driver Supply Input; voltage to drive the buck converter

powerstage

8

Supply Voltage Input; buck converter input voltage; external

blocking capacitor necessary.
