Abstract (English):
The article provides results of engineering design of switching power supply for light-emitting diodes with application current’s sources. Propose a schematic design on base PWM-controller with two transistor keys. Represented results of computer imitation design of power supply at CAD TINA-TI on base of engineering design spice macros IC of PWM-controller.

Keywords:
switching power supply, current key, pulse width modulation, imitation simulation, spice macros
