* NOTES FOR SIMULATION\n \nPlease read the following notes carefully since the model behaves differently from the user \ninterface for the LTC3887-1.\n \n(1) PMBus communication and memory address related functions and pins are not modeled. \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 \n \nDESCRIPTION OF PARAMETERS\n \nThe following parameters can be defined by right-clicking on the LTC3887-1 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 \nVIN_ON & VIN_OFF -- in volts, set the unit start/stop input voltages.\nVout_0 & Vout_1 -- in volt, set output voltages respectively.\nIlim0_range & Ilim1_range -- set maximum sensed peak current range, with value 0 for low 50mV and 1 for high 75mV.\nOC_limit0 & OC_limit1 -- set ratio of peak current limit to the maximum value defined by Ilimit_range.\n It must be one of values: 0.5, 0.572, 0.642, 0.714, 0.786, 0.858, 0.928, 1.\nMode_II -- sets light load operation mode: 0 for discontinuous, 2 for forced continuous.\nFault_response -- sets the response mode of the unit to occuring faults:\n 0 for ignore, 1 for latch-up, 2 for hiccup after Retry_delay time.\nRetry_delay -- in sec, sets the timer before the LTC3887-1 turns on after a fault.\n \nFreq -- in Hz, sets switching frequency as one of values of 250k, 350k, 425k, 500k, 575k, 650k, 750k, 1000k.\n FREQ_CFG pin needs to float or short to VDD25.\nPHs_0 & PHs_1 -- in degree, set phase angle related to SYNC signal. \n Certain combinations are restricted as in data sheet.\n FREQ_CFG pin needs to float or short to VDD25.\nTon0_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.\nToff0_delay & Toff0_fall; Toff1_delay & Toff1_fall -- in sec, set delay and soft-off timers for \n channel0 and channel1. \nVout0_range & Vout1_range -- set maximum output range, with value 0 for 5.5V, value 1 for 2.75V.
