r tube RCC, etc., can be done. Advantage of low cost, reliability is good. Because the average price of switching power supply chip is not only good, but after extensive use are the classic products. In fact, as this IC is generally integrated MOS, MOS than the 9910 plus convenient, but control more complex, require the addition of constant current control device, you can use transistors or operational amplifier. Magnetic components can be inductive character of labor, can also be used with a ga
