Function
Reference Input; an external resistor from this pin to GND determines the
reference current and the oscillator frequency
Reset Output; open drain output from reset comparator with an internal pull-up
resistor
Watchdog Input; input for the watchdog control signal from the controller
Ground; analog signal ground
System Enable Output; open drain output from Watchdog fail-circuit with an
internal pull-up resistor
Buck-Converter Compensation Input; output of internal error amplifier; for
loop-compensation connect an external R-C-series combination to GND
Supply Voltage Output; buck converter output; external blocking capacitor
necessary
Buck Converter Output; source of the integrated power-DMOS
Boost Converter Input; input supply voltage of the IC; coming from the boost
converter output voltage; buck converter input voltage
Buck Driver Supply Input; voltage to drive the buck converter powerstage
Boost Status Output; open drain output from boost PWM comparator
Boost Converter Feedback Input; connect boost voltage divider to this pin;
internal reference is the boost feedback threshold V_BOFBTH
Boost-Ground; power signal ground; source of boost converter power-DMOS
Boost Converter Input; drain of the integrated buck converter power-DMOS
