Description

VREF

Analog output

Internally generated DC-DC voltage reference (to be

connected to external 10 nF capacitor)

ROW0

Open drain

output

Status channel 1-2

ROW1

Open drain

output

Status channel 3-4

ROW2

Open drain

output

Status channel 5-6

ROW3

Open drain

output

Status channel 7-8

Open drain

output

Power Good diagnostic, active low

FAULT

Open drain

output

Fault indication, active low

TWARN

Open drain

output

IC case warning temperature detection, active low

Analog input

Step-down feedback input. The output voltage,

directly connected to this pin, results in an output

voltage of 3.3 V. An external resistor divider is

required for higher output voltages

GND

Ground

PHASE

Power output

Step-down output

BOOT

Power output

Step-down bootstrap voltage. Used to provide a

drive voltage, higher than the supply voltage, to

power the switch of the step-down regulator

Not connected
