Hi all,
I stumbled over a chip made by TI, the PTN78060W stepdown switching regulator.
It offers many good properties, such as 3A output current, wide input voltage range, wide voltage output adjust, high efficiency (up to 96%), undervoltage lockout and overtemperature shutdown.
Needless to say that I ordered a free sample to experiment with it.
So far I have made a basic circuit for a regulated output of 2.5 to 22V. The board dimensions are really small for the power the chip supplies: 2.96X1.17inches.
Everybody is welcome to participate improving the circuit, e.g. to gain an output voltage starting at zero Volts.

P.S. D1 and D2 should be 1N5401![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
