* Please read the following notes carefully since the model behaves differently from the user \ninterface for the LTC3889.\n \n(1) PMBus communication and memory address related functions and pins are not modeled.\n \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 \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 \n(4)The following parameters can be defined by right-clicking on the LTC3889 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 \n DRVSet - Select DRVCC level; 0 - 6.3V; 1 - 7.4V; 2- 9.0V \n VIN_ON & VIN_OFF -- in volts, set the unit start/stop input voltages; \n Freq -- in Hz, sets switching frequency as one of values of 85k, 100k, 125k, 150k, 200k, 250k, 275k, 300k, 350k, 425k, 500k. \n Freq_cfg pin needs to float or short to VDD25, to make the value be in effect;\n Sync -- value that sets the switching frequency phase offset with respect to the falling edge of the SYNC signal; \n Certain combinations are restricted as in data sheet. Phase_cfg pin needs to float or \n short to VDD25, to make the value be in effect; \n \n Sync SYNC TO 0 SYNC TO 1\n 0 0 180 \n 1 90 270 \n 2 0 240 \n 3 0 0 \n 4 120 240 \n 5 60 240 \n 6 120 0\n \n Ton0_delay & Ton0_rise; Ton1_delay & Ton1_rise -- in sec, set delay and soft-start timers for \n channel0 and channel1. Initialization time is not modeled; \n Toff0_delay & Toff0_fall; Toff1_delay & Toff1_fall -- in sec, set delay and soft-off timers for \n channel0 and channel1;\n Vout_0 & Vout_1 -- in volt, set output voltages respectively. Vout_cfgn pin needs to float or \n short to VDD25, to make the value be in effect;\n Vout0_range & Vout1_range -- set maximum output range, \n with value 0 for 40V, value 1 for 8V;\n Ilim0_range & Ilim1_range -- set maximum sensed peak current range, \n with value 0 for low (50mV), and 1 for high (75mV);\n Iout0_OC_Fault_Limit & Iout1_OC_Fault_Limit -- the IOUT_OC_FAULT_LIMIT command sets the value \n of the peak output current limit, in amperes. (Iout_Cal_Gain = Rsense value)\n \n For Ilim0_range=0 For Ilim0_range=1\n 1 for 50mV/Iout_Cal_Gain 1 for 75mV/Iout_Cal_Gain\n 0.928 for 46.4mV/Iout_Cal_Gain 0.928 for 69.6mV/Iout_Cal_Gain \n 0.858 for 42.9mV/Iout_Cal_Gain 0.858 for 64.3mV/Iout_Cal_Gain \n 0.786 for 39.3mV/Iout_Cal_Gain 0.786 for 58.9mV/Iout_Cal_Gain\n 0.714 for 35.7mV/Iout_Cal_Gain 0.714 for 53.6mV/Iout_Cal_Gain \n 0.642 for 32.1mV/Iout_Cal_Gain 0.642 for 48.2mV/Iout_Cal_Gain \n 0.572 for 28.6mV/Iout_Cal_Gain 0.572 for 42.9mV/Iout_Cal_Gain \n 0.5 for 25mV/Iout_Cal_Gain 0.5 for 37.5mV/Iout_Cal_Gain\n \n Mode_II -- sets light load operation mode: 0 for discontinuous, 1 for forced continuous;\n Fault_response -- sets the response mode of the LTC3889 to occuring faults:\n 0 for ignore, 1 for latch up, 2 for Hiccup after Retry_delay time;\n Retry_delay -- in sec, sets the timer before the LTC3889 turns on after a fault;\n gm0 & gm1 -- transconductance of the error amplifier. It must be between 1m mho and 5.73m mho;\n Rth0 & Rth1 -- Compensation resistor. It must be set between 0k ohms and 62k ohms;
