Pin Definitions and Functions

Symbol Function

R

Reference Input; an external resistor from this pin to GND

determines the reference current and the oscillator frequency

RO

Reset Output; open drain output from reset comparator with an

internal pull up resistor

WDI Watchdog Input; input for the watchdog control signal from the

controller

GND Ground; analog signal ground

SEN

System Enable Output; open drain output from Watchdog

fail-circuit with an internal pull up resistor

BUC

Buck-Converter Compensation Input; output of internal error

amplifier; for loop-compensation connect an external R-C-series

combination to GND

VCC

Supply Voltage Output; buck converter output; external blocking

capacitor necessary

BUO Buck Converter Output; source of the integrated power-DMOS
