LTspice IV can help you easily create your own schemes in order to simulate switching regulators.

LTspice IV is a high performance SPICE simulator, schematic capture and waveform viewer with enhancements and models for easing the simulation of switching regulators.

Capacitors and inductors can be modeled with series resistance and other parasitic aspects of their behavior without using sub-circuits or internal nodes. Also, a simulation circuit element was developed for power MOSFET's that accurately exhibits their usual gate charge behavior without using sub-circuits or internal nodes.

Version 17.1.15 is a freeware program which does not have restrictions and it's free so it doesn't cost anything.
