Device power supply.
Operative voltage is 12V ±15%. Filter with 1μF MLCC to SGND.
All the internal references are referred to this pin. Connect to the PCB
signal ground.
Error amplifier output.
Connect with an R
be disabled by grounding this pin.
Error amplifier inverting input.
Connect with a resistor R
Offset current programmed by OS is sunk through this pin.
A current proportional to the total current read is sourced from this pin
according to the current reading gain.
Short to FB to implement droop function, if not used, short to SGND.
Output voltage monitor.
It manages OVP and UVP protections and PWRGOOD. Connect to the
positive side of the load for remote sensing. See
