Description

FAULT

Fault Pin, Active Low, Pseudo Open-Drain Output. FAULT is high impedance when no faults are detected and is

asserted low when certain faults are detected, including an open circuit in current mode, a short circuit in voltage

mode, a CRC error, or an overtemperature error. Connect FAULT to VLOGIC with a 10 kΩ pull-up resistor.

AVSS

Negative Analog Supply. The voltage range on this pin is from 0 V to −33 V. If 0 V is applied, only current output

mode is supported.

−VSENSE

Sense Connection for Negative Voltage Output Load Connection in VOUT Mode. −VSENSE must stay within ±10 V of

AGND for specified operation. Connect a series 1 kΩ resistor to −VSENSE. If remote sensing is not used, short −VSENSE

to AGND via a series 1 kΩ resistor.

CCOMP

Optional Compensation Capacitor Connection for the VOUT Buffer. Connect a 220 pF capacitor between CCOMP and

VIOUT to allow the voltage output to drive up to 2 μF. The addition of this capacitor reduces the bandwidth of the

output amplifier and increases the settling time.

+VSENSE

Sense Connection for the Positive Voltage Output Load Connection in VOUT Mode. If remote sensing is not used,

short +VSENSE to VIOUT via a series 1 kΩ resistor.

VIOUT

Voltage or Current Output Pin. VIOUT is a shared pin that provides either a buffered output voltage or output current.

EPAD

Exposed Pad. Either connect the exposed pad to the potential of the AVSS pin, or leave the exposed pad electrically

unconnected. For enhanced thermal performance, thermally connect the exposed pad to a copper plane.
