TEXT -128 -256 Left 2 ;Please read the following notes carefully since the model behaves differently from the user \ninterface for the LTC7880.\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 LTC7880 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 PHs_0 & PHs_1 -- in degree, set phase angle related to 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 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 60V, value 1 for 30V;\n Ilim0_range & Ilim1_range -- set maximum sensed peak current range, \n with value 0 for low (50mV), and 1 for high (75mV);\n Iin0_OC_Fault_Limit & Iin1_OC_Fault_Limit -- sets the value of the peak input current limit, in amperes.\n For Ilim0_range=0\n 1 for 50mV/Iin_Cal_Gain; 0.928 for 46.4mV/Iin_Cal_Gain; 0.858 for 42.9mV/Iin_Cal_Gain; \n 0.786 for 39.3mV/Iin_Cal_Gain; 0.714 for 35.7mV/Iin_Cal_Gain; 0.642 for 32.1mV/Iin_Cal_Gain \n 0.572 for 28.6mV/Iin_Cal_Gain; 0.5 for 25mV/Iin_Cal_Gain \n For Ilim0_range=1\n 1 for 75mV/Iin_Cal_Gain; 0.928 for 69.6mV/Iin_Cal_Gain; 0.858 for 64.3mV/Iin_Cal_Gain; \n 0.786 for 58.9mV/Iin_Cal_Gain; 0.714 for 53.6mV/Iin_Cal_Gain; 0.642 for 48.2mV/Iin_Cal_Gain \n 0.572 for 42.9mV/Iin_Cal_Gain; 0.5 for 37.5mV/Iin_Cal_Gain \n Mode_II -- sets light load operation mode: 0 for discontinuous, 1 for forced continuous;\n Fault_response -- sets the response mode of the LTC7880 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 LTC7880 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;
