Description

UC2843AQ Overview
The UC2843 is a versatile base part number that offers a single output and a maximum output current of 200mA. Its input voltage-nom is 15V, but it can still operate with a minimum input voltage of 8.2V. This makes it suitable for a wide range of applications. However, it should be noted that its part status is now considered obsolete, meaning it may not be readily available in the market. Additionally, its ECCN code is EAR99, indicating that it is not subject to any special export controls. The terminal finish of this part is matte tin (Sn), providing a reliable and durable connection. It also features frequency control as its main control feature, but it does not have a synchronous rectifier.
