* Generated by LTspice 26.0.1 for Windows.
* Please read the following notes carefully, since the model presents different user interface\nthan the real part does.\n \n(1) All communication and memory address related functions and pins are not modeled. \n \n(2) Changes to all parameter values during the simulation running will not be in effect, unless the\nsimulation is stopped and restarted. This is different from the operation of the part, which will\n respond to the commanded changes while running. \n \n(3) MOSI is used as input for SPIS_DAC. Since LTspice cannot convert digital data into analog,\nthe SPIS_DAC signal must be converted first into equivalent analog voltage before starting the\nsimulation.\nExample, 0xFF000000 = 2.5V while 0x00000000 = 1.25V and 0x00FFFFFF = 30nV.\n \n(4) The following parameters can be defined, by right-clicking the symbol of LT8722. Different \nnomenclature from the datasheet is adopted here. If any value of these parameters are set beyond \nthe scope described in the datasheet, the resulting simulation outcomes are not meaningful.\n \n ENABLE_REQ -- 1 or 0, sets the ENABLE_REQ command to either 1 or 0.\n SWEN_REQ -- 1 or 0, sets the SWEN_REQ command to either 1 or 0.\n VCC_VREG -- 1 or 0, set the regulation voltage of Vcc pin 1 for 3.4V, 0 for 3.1V\n FREQ_SET -- 0 to 7, set the switching frequency of the Buck converter, 0 --> 500Khz, 1 --> 1Mhz\n 2 --> 1.5Mhz, 3 --> 2Mhz, 4 --> 2.5Mhz and 5,6,7 --> 3Mhz.\n FREQ_ADJ -- 0 to 3, adjusts the switching frequency of the Buck converter +/- 15% above the \n set frequency,\n 0 --> 0%, 1 --> +15%, 2 --> -15%, and 3 --> 0%.\n SYS_DC -- selects the duty cycle control range,\n 0 --> 20% to 80%, 1 --> 15% to 85%, and 2, 3 --> 10% to 90%.\n DAC_ILIMP -- 0 to 462 where 0 corresponds to 6.8A while 462 to 637.44mA with 13.28mA per \n step.\n DAC_ILIMN -- 48 to 511 where 48 corresponds to -637.44mA while 511 to 6.8A with -13.28mA \n per step.\n OV_CLAMP -- 0 to 15, sets the positive output voltage limit, See details on the datasheet.\n UV_CLAMP -- 0 to 15, sets the negative output voltage limit. See details on the datasheet.\n VC_INT -- 0 to 7, sets the initial peak inductor current limit. See details on the datasheet.\n AMUX -- 0 to 15, selects which signal Aout pit will output. See details on the datasheet.\n AMUX_TEST -- 0 or 1, provides additonal setting for signal selection on Aout Pin,\n See details on the datasheet.
