BQ2002CSN

The BQ2002CSN is a PMIC – Battery Chargers device with a range of applications in varied industries. It is a high performance device which offers superior performance and reliability compared to other similar devices in its class. The BQ2002CSN is a non-isolated flyback converter which is extremely efficient, offering a high charging rate with minimal losses. The device can also provide output voltage control, making it a very flexible solution for battery charging.

The BQ2002CSN has a wide range of applications in industries from industrial to consumer, automotive, medical and telecommunication. It is designed to provide portable power for industrial and consumer batteries such as lithium-ion (Li-ion) and NiMH. It can be used for portable electronics like laptop, portable media players and other equipment. Furthermore, the device can be used for automotive battery charging systems, medical device battery packs and for telecommunication backup powering.

The device has a maximum input voltage of 110V and its output voltage range is set from 2.8V to 18V, which allows its use for different battery types. In addition, the device has an efficiency of 95% and a maximum output power of 25W. The device is also equipped with overvoltage and over-temperature protection which ensure safe battery charging at all times. The device also offers short-circuit protection and auto-shutdown capability when the load Voltage drops below the set threshold.

The BQ2002CSN device also offers a built-in AC/DC converter which allows it to operat both AC and DC sources. This feature makes it ideal for applications where there is no direct access to a power source. In addition, the device is equipped with a multi-level power factor correction capabilities and wide operating temperature range for efficient charging in different ambient conditions.

The BQ2002CSN device utilizes the flyback topology which provides a wide range of features. The first is a low output ripple which eliminates the need for additional input filters, allowing improved efficiency and power density.
