TEXT 1144 -864 Left 2 ;NOTES FOR SIMULATION\n \nPlease read the following notes carefully since the model behaves differently from the user \ninterface for the LT7182S.\n \n(1) PMBus communication and memory address related functions and pins are not modeled, \nincluding SDA, SCL, WP. \n(2) Changes to parameter values while the simulation is running will not take effect unless the\nsimulation is stopped and restarted. This is different from the way the part operates which will\nrespond to the changes while running. \n(3) SHARE_CLK is not modeled. The default time reference of LTspice is used as the common time \nbase for all time-related parameters.\n(4) Resistor Configuration pins are not modelled (VOUT0_CFG, VOUT1_CFG, ASEL)\n(5) Initialization time is not modelled. After power is applied to PVIN0 or EXTVCC, the real LT7182S\nrequires 13ms (typical) before power conversion or communication can begin.\n \n \nDESCRIPTION OF PARAMETERS\n \nThe following parameters can be defined by right-clicking on the LT7182S symbol.\nThe nomenclature used here differs from the one in the data sheet. If any value of these parameters is\nset beyond the scope described in the data sheet, the resulting simulation will not be meaningful.:\n \nFREQUENCY_SWITCH -- in Hz, sets switching frequency for both channels\n \nThe parameters below are set independantly for each channel (0 and 1): \nVOUT_COMMAND_n -- in volt, sets output voltage\n \nTON_DELAY_n & TON_RISE_n -- in sec, set turn-on delay and soft-start time\nTOFF_DELAY_n & TOFF_FALL_n -- in sec, set turn-off delay and soft-off time \n \nIlim_range_n -- selects inductor valley current limit option:\n 0 positive valley current limit of 3A, negative valley current limit of -2.3A\n 1 positive valley current limit of 4.5A, negative valley current limit of -3.4A\n 2 positive valley current limit of 6.5A, negative valley current limit of -4A\n 3 positive valley current limit of 8.5A, negative valley current limit of -4.25A \n \nPulseSkipMode_n --sets operation mode: 1 for pulse skip mode, 0 for forced continuous conduction mode\n \nFCM_DURING_TOFF_FALL_n -- if set to 1, channels uses FCM during soft-off ramp-down,\n regardless of PulseSkipMode_n\n \nGMEA_control_n --Sets Error Amp parameters, x=0 to 7\n GmEA = 0.15mS*(x+1) (relative to VSENSE)\n \nHPLV_n -- if set to 1, selects High-Performance Low-Vout mode (max 1.375Vout, GMEA is 4X higher)\n \nRITH_n --in ohm, programmable internal compensation\n \nCITH_n --in Farad, programmable internal compensation\n \nMFR_PWM_PHASE_n -- in degree, sets the channel phase delay in 15-degree increments \n (this is relative to the SYNC input clock if present).\n \nOutput_discharge--0 for disabled, 1 for 250 Ohm discharge engaged when channel is off or ramping off\n \nVout_UV_Fault_Limit and Vout_OV_Fault_Limit --- in volt, set the fault limits for the PGOOD and /FAULT outputs\n Note channel shuts down if VOUT OV FAULT occurs, or VIN>23.2V, or /FAULT pin is pulled low externally\nVout_UV_Warn_Limit and Vout_OV_Warn_Limit-- in volt, set the warning limit for the /ALERT output
