I use a MINI2440 128M board. I don't know if the LCD is a 3.5-inch LCD from TPO or NEC. The screen was split into two halves when it was ported over. I modified the parameters in the arch/arm/mach-s3c...
[align=left][color=#000]The synchronous buck converter power topology is used in many industrial and automotive applications; these applications also require low conducted and radiated emissions to en...
What does the saturation of common-mode inductors mean? Is it the saturation of magnetic flux? So when winding common-mode inductors, how can we prevent the inductor from saturating when a large insta...
Dear experts, I have seen many people in the forum who are new to MSP430 microcontrollers and do not know how to program, how to call each module, and how to play with low power consumption. The follo...
On the afternoon of September 28, I met a person named sunboyljp in our forum who posted a message asking for SKYPE on CE. At that time, my colleague and I made a bet: 1000 points for the transaction....
Emergency hand-held lamps powered by 6V maintenance-free batteries are widely used in rural areas. The charger used is a transformer step-down and single diode half-wave rectifier, and the charging...[Details]
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]
