Filter with 1 µF MLCC to SGND. 2SGND All the internal references are referred to this pin. Connect to the PCB Signal Ground. 3 COMP Error amplifier output. Connect with an RF - CF to FB. The CORE section or the device cannot be disabled by grounding this pin. 4FB Error amplifier inverting input. Connect with a resistor RFB to VSEN and with an RF - CF to COMP. Off- set current programmed by OS is sunk through this pin. 5DROOP 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. 6 VSEN Output voltage monitor. It manages OVP and UVP protections and PWRGOOD. Connect to the positive side of the load for remote sensing. See Section 7 for details. |
