PSoC gurus: try design this.

[technix]

The general idea of a mixed-mode power supply have been on my mind for quite a while now. I have a semi-working design but before committing the design to manufacture I would like to ask the PSoC gurus here to match my design using a PSoC.

Specifications:
* Input: 20V DC, 3.2A maximum
* Output: 0-15V, 5A, 50W maximum (whichever comes first)
* Topology: Bypassable MOS Low drop-out linear regulator with bypassable two-phase CMOS synchronous rectifying tracking pre-regulator.
* Control surfaces: touchscreen, TCP/IP network
* Protection: Constant current & constant voltage modes automatic switchover, power element thermal shutdown

Components allowed:
* PSoC: One PSoC of your choice, only DIP, SOIC and QFP packages allowed.
* Power MOSFETs: Either Two IRF7204 & two IRF7470 or four IRF7470 for the switch-mode section, one IRF4905 or one IRL540N for linear section.
* Passive & others: Three power inductors of any value or package, three high value electrolytic capacitors. Any amount of 0603 surface mount resistors, capacitors or inductors of your choice. Any amount of SOT-23 transistors or diodes of your choice.
* Since this is the strength of PSoC, no integrated circuits other than the PSoC, up to two IR2101 and up to one DP83848 is allowed. (The touchscreen module does not count here)

Don't be shy, show us that semi-working design here ...
