Abstract: TOPSwitch-II device is a new type of integrated chip that combines PWM/MOSFET. Using it to make high-frequency switching power supply can not only simplify the circuit, but also improve the ...
When using FPGA to prototype ASIC, the number of ports between modules inside ASIC is large, while the number of pins between multiple FPGAs is relatively limited. How do you solve this problem? Thank...
For the lines drawn by Protel series and AD series software, no matter which layer (including routing layer, Keepout layer, etc.) they are drawn on, when you double-click to open the line properties, ...
My circuit converts 28 channels of TTL to LVDS, and then to 28 channels of TTL (the chip used is DS90CR286/5). My pin assignment is based on the cameralink protocol, and no problems were found after c...
My motherboard is pxa270. I used to use Ucb1400 driver, but now I use Wolfson9715. I don't know how to modify the driver. How to switch the audio channel? Can an expert give me some advice?...
High efficiency and low standby power consumption are two major challenges in today's switching power supply design. Resonant topology or LLC topology is becoming increasingly popular because it ca...[Details]
