The PIC Programmer, which is built on the converter circuit MC34063A 1.5 Ampere Step−Up/Down Inverting regulator, can be used for different applications where the feeding section is used as a separate floor. most likely 60ma too little more power can’t be taken? it will be asked 🙂 I guess it can be done by strengthening the integrated output with a mosfet, it is necessary to try, and it will be necessary to increase the power of the core used.
MC34063A USB DC DC Converter
do not have the network adapter, so you make changer for power programmer. USB interface on the outer vyvodech connector voltage 5V / 500 mA, which to us is sufficient to power converters. Drive voltage is transformed for the 5th to the 20th power programmer. Compiled changer connect for free USB on the computer.If changer works and the output voltage, lighting up the green diode LED

High Voltage DC to DC Converter Circuit LM2576
The base consists of circuit LM2576-ADJ, belonging to the group of highly integrated circuits, so that the proper function of just a few external components. Basically, it is a step-down converter with adjustable output voltage for constant current up to 3A. When buying circuit is necessary to buy a circuit with the surname Adj. Similarly labeled perimeter without Adj from production fixed at 5V output voltage without the possibility of regulation. The output voltage can be as same as input or less. The opposite function with only a slight modification of the wiring should be used as circuit LM2577-adj
