IRF520 Suppliers

771 developed in the efficiency of aircraft up to 95% of the power LED driver

In Electronic Infomation Category: 7 | on 2011/4/27 11:26:12

Recently, the China Aerospace Science and IRF520 datasheet and Technology Corporation Hospital 771 Nine Power Division to drive the circuit as a breakthrough, high-reliability design is complete constant current power supply, and IRF520 price and achieved significant results stage. Although the life span of LED lighting is generally more than 5 million hours, but with matching drive power is only 10,000 hours life around, unable to match the LEDs life, becoming one of the bottlenecks restricting LED lighting. Section Xiaofei to the project team for the responsible person for driving power through a single wizard, is subjected to high peak current characteristics, combined with its turn-on threshold voltage and IC IRF520 suppliers and V / I curve, designed a new LED driver circuit, all the semiconductor devices and resistors. Life of the drive circ...
