2006-3-15: Integrated Flyback DC/DC is available now.
2006-3-15: Detail Specification function is upgraded. You are able to set the detail spec. before and after initializing the design.
PowerESIM provides automatic closed loop design for power converters
  • Gain margin & phase margin are very often part of a power supply specification.
  • Equations for power converter control loop are often complicated and not explicit.
  • A lot of time and effort is needed to tune component values around the error amplifier.
  • PowerESIM provides all component parameters needed at a click.
  • Simply specify the gain margin and phase margin on the bode plots by clicking "compensation setting" in Loop Analysis.
  • After the requirements are set simply click "Automatic Compensation".
  • All relevant component values are given together with a simulated bode plot for your reference.
  • PowerESIM makes closed loop design easy and fun.
Tips on PowerESIM
Transient Analysis

In addition to closed loop design you may check the performance of your design by checking the response to step change in load current. Click "Transient Analysis" under "Loop Analysis"
Define your load current step and check the output voltage transient waveform. See whether it meets your voltage overshoot requirement.
