This is the 230th content shared by the platform.In the era of the Internet of Things, power management chips have evolved from simple voltage converters to the “smart energy hub” of systems. The Texas Instruments TPS65262, as a representative of the third generation of multi-output synchronous buck converters, not only redefines the performance standards of … Read more
Original:https://mp.weixin.qq.com/s/2ACNTsl_JQSMwvWsZf55zw 1. Introduction During the use of a computer, shutting down and rebooting are the first two operations learned. Similarly, these two operations exist in Linux, allowing for shutdown and reboot. This is the subject to be described here. In the Linux Kernel, mainstream shutdown and reboot are implemented through the “reboot” system call (for … Read more
Introduction In the field of high-efficiency power conversion, the Asymmetric Half-Bridge (AHB) topology has become a core design solution for high-density power modules, electric vehicle chargers, and industrial power systems due to its simple structure, low switching losses, and soft-switching characteristics. As the “brain” of the AHB architecture, the AHB controller chip achieves efficient driving … Read more

Original: https://mp.weixin.qq.com/s/HJihdfu9zVYEuvHVV0WXwQ 1. Introduction Conventional power management methods in Linux systems include shutdown (Power off), standby (Standby or Hibernate), and reboot (Reboot). These methods were used during the era of PCs or servers before the widespread adoption of embedded Linux. In that primitive era of computer science, driven by Moore’s Law, humanity was focused on … Read more
