PCB Design Considerations for RK3588 VDD_LOGIC Power Supply 1. The copper width for VDD_LOGIC must meet the current requirements of the chip. The copper connected to the chip’s power pins should be sufficiently wide, and the path should not be too severely interrupted by vias. It is essential to calculate the effective line width and … Read more
In the process of developing and debugging applications using STM32 microcontrollers, we often encounter various anomalies. A significant portion of these issues are related to the power supply. The power supply is critical and essential for any electronic product, yet during actual development and debugging, we sometimes inadvertently neglect it. Here, I share a few … Read more
The CPU fan is intermittently stopping, causing the computer’s temperature to rise steadily. Various troubleshooting steps have been taken; the computer can boot without blue or black screens. However, the fan keeps stopping intermittently. The memory sticks have been cleaned, and the power supply has been checked, but the cause remains elusive (it is likely … Read more
DC-DC Remote Feedback Design for RK3588 Core Power Supply The 100ohm feedback resistor needs to be placed close to the output capacitor. One end of the resistor connects to the DC-DC output capacitor, while the other end connects to the VOUT feedback pin of the PMIC, and simultaneously to the farthest load of the same … Read more
