The P1 sets the trigger point of the pulse. The transistor T1 works as the actual regulator by switching a relatively high current with a maximum of 5 amperes. The power supply voltage must be between ...

Voltage regulator IC’s, with 3 pins, from LM7805 and LM7812 series are excellent for usage in voltage regulator circuits. If you need higher currents, up to 3 A, you must add a complementary ...

A feedback circuit commonly used in isolated dc-dc converter applications uses a shunt regulator (such as the ATL431) and an optical isolator to feed the output voltage back to the pulse-width ...
