Powering today’s microprocessors: Old myths versus modern technology phase converters running at 1 MHz per phase, using 2-mΩ MOSFETS and 100-nH SMT inductors to deliver 150A at 1V are no longer a novelty. However, they are relatively inefficient and cannot be packed tightly on the PCB due to excessive heating. Thus, the higher switching frequencies

DDR2 function introduction 1. The best auxiliary helper for testing, the most convenient and practical maintenance tool. 2. Twelve years of experience in programming in the DRAM memory industry. 3.Can test DDR2 16M * 16, DDR2 32M * 8, DDR2 32M * 16, DDR2 64M * 8, DDR2 64M * 16, DDR2 128 * 8

Sometimes, when you troubleshoot a MacBook, MacBook Pro or MacBook Air problem you need to turn it on without using the power button. Is it possible? Yes, it is! In these laptops (unibody style) the power button is permanently attached to the keyboard. Basically, it’s a part of the keyboard as you can see on the

Usual maintenance, often encounter the CPU power supply filter capacitor with a capacitance, Toshiba laptop, more commonly, failure phenomenon is not displayed: boot current transition less, the adapter does not show battery can be displayed, just need it replaced can use all sorts of strange failure of the occasional Huaping, we look at the artwork

Such as title, the customer sent, the boot is not significant, then there is an external display, you can normally enter the system, offer the player, this board is onboard the CPU’s 945 chip set was small, had to be welded visual Northbridge, CPU power, however, welded over, in short, very messy, looking very unhappy.
