The popular LM317 voltage regulator IC is designed to deliver not more than 1.5 amps, however by adding an outboard current boost transistor to the circuit it becomes possible to upgrade the regulator circuit to handle much higher currents, and upto any desired levels. You might have already come across the 78XX fixed voltage regulator […]

Simple Buck-Boost Converter Circuits Explained
In this post I have explained s few simple DC to DC buck-boost converter circuits which can be used for either stepping up the input DC voltage or stepping down the input DC voltage to specific output DC voltage levels. Since a buck-boost converter allows the input voltage to be either stepped up or stepped […]
Underwater LED Boost Converter Circuit with Dimmer
In this post I have explained an LED controller circuit having a boost and dimming facility specifically designed for underwater shooting application. The idea was requested by Mr. Svein. The Circuit Request I came across your blog at https://www.homemade-circuits.com and thought I’d ask you a question regarding building or modifying a LED driver. I planning […]
