Based on the LTC3862, this circuit consists of a DC-DC converter capable of operating with input voltages lower than the desired output. MOSFET admits equivalent.
One of the problems with common 3-terminal regulators is that the internal reference, normally 1.25 V,...
This circuit found in French documentation, works with 15 V logic, but can be modified to TTL or 5...
We found this circuit in a 1972 documentation. The transistor, in fact, is a unijunction that can...
