DESCRIPTION
Power-good. This pin transitions high 100ms after output voltage stabilizes within regulation band.
Selectable open drain or push-pull output. Factory default is open drain.
Digital ground. Common return for digital signals. Connect to low impedance ground plane.
Clock synchronization pin. Used to set switching frequency of internal clock or for synchronization to
external frequency reference.
Output voltage select pin. Used to set VOUT set-point and VOUT max.
Serial address select pin. Used to assign unique SMBus address to each IC.
Serial clock. Connect to external host interface.
Serial data. Connect to external host interface.
Serial alert. Connect to external host interface if desired.
Loop compensation select pin. Used to set loop compensation.
Configuration pin. Used to control the SYNC pin, sequencing and enable tracking.
Soft-start pin. Used to set the ramp delay and ramp time, sets UVLO and configure tracking.
Track sense pin. Used to track an external voltage source.
Output voltage positive feedback sensing pin.
Common return for analog signals. Connect to low impedance ground plane.
Power ground. Common return for internal switching MOSFETs. Connect to low impedance ground plane.
I/O
Switching node (level-shift common).
