The rapid development of the electronics industry is inseparable from electricity. Since we need to use electricity, it involves a control circuit and a power circuit. A key part of the power circuit is the Power Management Integrated Circuit (PMIC). For those with years of experience in the electronics industry or newcomers to power design, … Read more
Whether for consumer electronics, industrial control, IoT devices, or for communication networks and automotive electronic systems, Power Management ICs (PMICs) are a critical part of the system. PMICs contain a large number of analog circuits, and due to uncontrollable factors during production, the final mass-produced analog circuits may differ from the initial design, affecting the … Read more
1. Introduction Recently, I received a board sent by the Breadboard Community, based on Nordic’s latest nPM1300 power management chip evaluation kit. When it comes to power management chips, people may be familiar with discrete chips for functions like boost/buck conversion, power monitoring, POR reset, and charge/discharge management. However, it is rare to see all … Read more
According to reports from Electronic Enthusiasts (Author: Zhou Kaiyang), last year Micron and several other memory manufacturers successively launched DDR5 memory. However, due to the high prices of DDR5 memory, which reached thousands on major platforms, coupled with the insufficient support from hardware such as CPUs and motherboards, this first batch of DDR5 memory did … Read more

Companies such as SAIC Group and CATL have announced plans for mass production of all-solid-state batteries. Globally, major battery manufacturers … Read more
1. What is PMIC Power Management Integrated Circuit (PMIC) is the Chinese term for 电源管理集成电路, which is characterized by high integration, encapsulating traditional multi-output power supplies into a single chip, making multi-power applications more efficient and compact. PMIC is an indispensable key component in today’s electronic devices, providing power for various devices from mobile phones … Read more
According to reports from Electronic Enthusiasts Network (by Li Ningyuan), there are three power supply design solutions—fully discrete, fully integrated, and partially integrated. Among these, integrated PMICs package traditional multi-output power supplies into a single chip, resulting in higher efficiency and smaller size for multi-power applications. This fully integrated power solution is essential in wearable … Read more
