*<Introduction >
*This document contains the SPICE model, application example for National Semiconductor's LM5030 100V Push-Pull Current Mode PWM Controller
*The LM5030 PWM controller contains all of the features needed to implement Push-Pull and Bridge topologies.
*<LM5030 Model>
*The LM5030 PSPICE Model contains all of the basic features including;
*- Internal Start-up Bias Regulator 
*- Single Resistor Programmable Switching Frequency
*- Internal Error Amplifier
*- Programmable Soft Start 
*- Dual Mode Over-Currrent Protection
*- Current Mode with Slope Compensation
*- Direct Optocoupler Interface 
*<Assumptions and limitations>
*Model & Example Assumptions;
*- The temperature for this model is 25C
*- ESR and ESL of capacitors are zero.
*- Wire DCR and leakage inductances of transformer are zero.
*- No parasitic elements of package. 
*Some functions/characteristics of LM5030 are not included in this model;
*- Thermal shutdown 
*- Oscillator Synchronization
*Some characteristics of LM5030 are included but not optimized
*- Gate driver capability 
*- Power consumption of controller  
*- SS discharging time 
*- Deadtime
*Also GND pin of LM5030 is internally tied to GND (node number 0)
*<Note>
*-To run the simulation a simulation profile should be added first--> click 'New Simulation Profile' 
*-The simulation takes around 1~3min actual time per 1mSec simulation on a 1.7GHz machine.
*-Vsupply should have a slope lower than 150V/Sec
