Preface
The application of lithium batteries continues to give birth to many cordless and portable Internet celebrity products, such as outdoor power supplies, power tools, inflatable pumps, high-power power banks, etc. This kind of products have a common feature, which is a high-capacity and high-power battery pack composed of multi-cell and multi-string batteries, which is inseparable from the buck-boost power chip behind the market application of these products. At present, a number of power chip companies have laid out this market early, aiming at the market pain points, and launched a series of step-up and down-voltage power chip solutions.
The English name of buck-boost is Buck-Boost, which can be both boosted and bucked as the name suggests. Regardless of whether the input voltage is lower, higher or equal to the voltage of the battery pack, the chip can automatically control the voltage boost or voltage down to realize the charging management of the battery pack. When the system needs to be discharged from the battery pack, the controller can reverse the output voltage of the battery voltage up or down to output the required voltage, which can also output below, above or equal to the battery pack voltage value.
With the announcement of Apple's autumn conference this year, the iPhone 15 series has fully transitioned to the USB-C interface, and the integration trend of electronic device interfaces is becoming more and more obvious. Nowadays, whether it is a smartphone, a smart watch or a variety of state-of-the-art electronic devices, it is common to use the USB-C interface for power supply.
In the past, there was a diversity of charging interfaces between electronic devices, resulting in users needing to carry different chargers when using different devices, which increased the inconvenience of use. After the buck-boost chip supports the USB-C standard, the power tool can be connected to various electronic devices through a unified USB-C interface, and through the support of the PD fast charging function of the electronic equipment, it can achieve a wider compatibility and provide users with a more convenient charging experience.
The 2024 (Spring) Asia Charging Exhibition will be held in Shenzhen on March 20-22, when a number of buck-boost chip companies will participate in the exhibition and release a variety of new products and reference designs.
