Microchip also has application notes with a lot of handy info.
A perfectly fit is a SMPS-buckregulator in combination with a MPPT algorithm to always get the maximum power out of the generator.
This is usually done with a microcontroller.
For 'braking' purposes you can add a dummyload to the system.
If you want high efficiency this is not simple.
For most Lead acid batteries maximum charging voltage is about 14V.
See the factory specs of the battery for precise info.
If you want to keep it simple you can build a 14V voltage regulator with a blocking diode behind it.
Have you got a brake...
Pmos used to be more expensive and have limited specs.
But more important nowadays is choosing between Nmos and Pmos in order to keep the schematic simple in regards to the steering of the gate.
And for such small currents an LM2575 will not raise your energy-efficiency.
The transformer is relatively the biggest energy waister here.
If you want low energy consumption use a ECO transformer or an SMPS power supply.
Re: Keypad Matrix
You can use a resistor network as shown in Microchips Application note 234:

Those bank warning messages are no problem.
In the ASM-file you can see that the bankswitch is performed correctly.
There is no reason to assume that the schematic and/or software is not ok.
Build it and test it !
:D
Re: RB0 problem
It looks like it your software is getting multi interrupts?
Never leave the INTpin open, so i would suggest a 10k pull down resistor.
Put a cap parrallel during your testing.
Is your power supply clean?
how to build power supply
Those solar panels barely give any power indoors. A waist to spent your money on that.
USB gives a direct electrical connection with your pc, not a good idea for a lab-powersupply.
Have you thought about a settable current limit? For me that is the first thing a...
step by step smps
Yes, i tried it with a transformer out of a PC power supply.
The 2 high voltage windings i have put in series. But i only got 100 Volts out of it....
Re: questions regarding the drop-out voltage of a DC regulat
Yes, suppose the output voltage is too low, there will be current flowing through the mosfet into the output capacitor.
Voltage will rise up until setpoint, then the feedback loop will lower the g-s voltage of the mosfet to zero. No...
