Current Mode by Robert Mammano Unitrode IC Corporation has since its inception been active in the development of leadingedge control circuits to implement stateoftheart pro gressions in power supply technology Over the years many new products have b Jro INTRODUCTIDN leekege inductence is often the lergest single factor in degrading the performance of a switching power supply The effects of leekage inductence in buck and boost regulfJtors differ markedly from flybeck buckboostJ circuits This pap This proposed spec defines limits for each harmonic component of the mains current thereby requiring power factor correction circuitry IEC 5552 har monic current limits are proportional to power input below 300W but current limits are absolute above Jump Start Guideline 1. Turn off the Power Supply for your safety, set the I/O switch on the back of power supply to the "O" status 2. Unplug the AC power cord from the power supply 3.

The IC has features such as safe operating area protection, thermal shut down, internal current limiting which makes the IC very rugged. Output currents up to 1A can be drawn from the IC provided that there is a proper heat sink. . Outline. DC-DC conversion and voltage regulation.
