* *************** READ ME **********************************************************************\n \nThis model does not cover the PMBUS and SPI functions of this IC.\nTherefore, many things controlled by the PMBUS are configured by CTRL + right click on the IC.\nShare_CLK is NOT modelled. The SYNC pin can only be used as an input and\nit is grounded when it is not used. CLK_OUT pin is provided to allow clock out function.\nResistor setting pins like Vout_CFG are not modeled.\nVout and PWM_config must be set by CTRL by right-clicking on the IC.\n \nFrequency_Switch sets the frequency in kHz between 250 and 1000.\nPWM_config controls the phasing and master/slave configuration of the 8 channels.\nA decimal number is used for the 3-bit binary number. The description starts on page 72 of the datasheet.\n \n# (PWM0: PWM1)\n7 (7 phase: 1 Phase)\n6 (6 phase: 2 Phase)\n5 (6 phase: 1 phase)\n4 (5 phase: 3 phase)\n3 (4 phase: 4 phase)\n2 (4 phase: 3 phase)\n1 (4 phase: 2 phase)\n0 (3 phase: 3 phase)\n \nVout0 and Vout1 program the output voltage in a range from 0.3 to 3.45V\nVout_trans_rate0 and Vout_trans_rate1 program the rate of movement of VOUT as the part is starting or margining (V/ms).\nGM0 and GM1 program the gain the Error Amplifier in range from 1 to 5.73mS\nIout_Cal_Gain should match the voltage gain of the chosen current sense (V/A)\nRith0 and Rith1 program the compensation resistor in series \n with Cithr on the output of the error amplifier in a range from 1k to 62k ohm\nTon_Min=45n programs the minimum on time of the PWM outputs\n \nOC_Limit0 and OC_Limit1 program the peak current limit of the each phase used for that converter. \n \nTon_Delay0 and Ton_Delay1 set the delay from when the RUN pin goes high until the soft-start begins\nToff_Delay0 and Toff_Delay1 set the delay from when the RUN pin goes low until the turn-off ramp begins\n \nVOUT_UV_Fault_Limit0 and VOUT_UV_Fault_Limit1 program the undervoltage fault limit for the Pgood output\nVOUT_OV_Fault_Limit0 and VOUT_OV_Fault_Limit1 program the overvoltage fault limit for the Pgood output\n \nSlave0 and Slave1 set slave channel. 0 disable,1 enable. If enabled the error amplifier is open circuit

TEXT 2824 1064 Left 2 ;*************** READ ME **********************************************************************\n \nThis model does not cover the PMBUS and SPI functions of this IC.\nTherefore, many things controlled by the PMBUS are configured by CTRL + right click on the IC.\nShare_CLK is NOT modelled. The SYNC pin can only be used as an input and\nit is grounded when it is not used. CLK_OUT pin is provided to allow clock out function.\nResistor setting pins like Vout_CFG are not modeled.\nVout and PWM_config must be set by CTRL by right-clicking on the IC.\n \nFrequency_Switch sets the frequency in kHz between 250 and 1000.\nPWM_config controls the phasing and master/slave configuration of the 8 channels.\nA decimal number is used for the 3-bit binary number. The description starts on page 72 of the datasheet.\n \n# (PWM0: PWM1)\n7 (7 phase: 1 Phase)\n6 (6 phase: 2 Phase)\n5 (6 phase: 1 phase)\n4 (5 phase: 3 phase)\n3 (4 phase: 4 phase)\n2 (4 phase: 3 phase)\n1 (4 phase: 2 phase)\n0 (3 phase: 3 phase)\n \nVout0 and Vout1 program the output voltage in a range from 0.3 to 3.45V\nVout_trans_rate0 and Vout_trans_rate1 program the rate of movement of VOUT as the part is starting or margining (V/ms).\nGM0 and GM1 program the gain the Error Amplifier in range from 1 to 5.73mS\nIout_Cal_Gain should match the voltage gain of the chosen current sense (V/A)\nRith0 and Rith1 program the compensation resistor in series \n                with Cithr on the output of the error amplifier in a range from 1k to 62k ohm\nTon_Min=45n programs the minimum on time of the PWM outputs\n \nOC_Limit0 and OC_Limit1 program the peak current limit of the each phase used for that converter. \n \nTon_Delay0 and Ton_Delay1 set the delay from when the RUN pin goes high until the soft-start begins\nToff_Delay0 and Toff_Delay1 set the delay from when the RUN pin goes low until the turn-off ramp begins\n \nVOUT_UV_Fault_Limit0 and VOUT_UV_Fault_Limit1 program the undervoltage fault limit for the Pgood output\nVOUT_OV_Fault_Limit0 and VOUT_OV_Fault_Limit1 program the overvoltage fault limit for the Pgood output\n \nSlave0 and Slave1 set slave channel. 0 disable,1 enable. If enabled the error amplifier is open circuit
