1 – 9V Variable Desktop Power Supply

Here the variable desktop power supply which will convert a high input voltage (12V) from the SMPS / PSU of a desktop computer into small output voltage (1.25 to 9 volts). This converter will be very beneficial for electronics hobbyists. An adjustable three-pin voltage regulator chip LM317T (IC1) is applied right here to deliver the… Read More »

Car Cigar Lighter to USB Power Socket

Nowadays, almost all computer systems have logic blocks for working with a USB port. A USB port, in practice, is capable of supplying more than 100 mA of continuous electric current at 5V to the peripherals which are hooked up with the bus. So a USB port could be utilized, without having any problems, for… Read More »

DC to DC Converter +5V to +12V

This is the fixed 5V to 12V DC to DC converter. The circuit application converts input voltage of 5V (range 4.5V-5.5v) to 12V fixed regulated DC output. The circuit built based National regulator monolithic IC LM2586 which is specifically designed for flyback, step-up (boost), and forward converter circuit applications. The LM2586 will require a heat… Read More »

5VDC to 12VDC LT1070 Boost Converter

This is a 5VDC to 12VDC boost converter circuit built based LT1070. The LT1070/LT1071 are monolithic high power switching regulators. They can be operated in all standard switching configurations including buck, boost, flyback, forward,inverting and Cuk. A high current, high efficiency switch is included on the die along with all oscillator, control and protection circuitry.
