Higher Variable Output Voltage from IC 7812
You may have often wondered whether it was feasible to get higher voltages than 12 V from a 7812 IC? In this short post I have explained how to configure the IC 7812 with a BJT stage, so that its output can be made variable for achieving any desired voltage higher than 12 V, without […]
12 V to 30 V High Current Boost Converter Circuit [Variable]
In this post I have explained how to make a high current boost converter circuit which will step up a 12 V DC to any higher level up to 30 V maximum, and at an impressive 3 amp current rate. This high current output can be further enhanced by suitably upgrading the inductor wire gauge […]
LM317 Variable Switch Mode Power Supply (SMPS)
So far in this website we have studied LM317 based linear power supply circuits, here I have explained how an LM317 can be executed as a variable switch mode power or SMPS with zero loss. LM317 as Linear Regulator We all know that an LM317 IC is internally designed to work as a linear voltage […]
0-60V LM317HV Variable Power Supply Circuit Diagram
The high voltage LM317HV series of ICs will allow to go beyond the traditional voltage limits of an LM317 IC and enable controlling supplies that may be as high as 60V. 0-60V Regulation with a Single IC LM317 Therefore now you can build a universal 0-60V regulated power supply circuit loaded with all the essential […]
