Description

UC3842D Overview
The Surface Mount Mounting Type is a popular choice for electronic components due to its compact size and ease of installation. The 14-SOIC (0.209, 5.30mm Width) Package/Case is specifically designed to fit this type of mounting, providing a secure and reliable connection. With an operating temperature range of 0°C~70°C TA, this component can withstand a wide range of environmental conditions. It is packaged in a Tube for convenient storage and transportation. However, it is important to note that this part is now considered obsolete, with the Base Part Number being UC3842. Despite this, it still serves a crucial function as a Step-Up/Step-Down converter, with a Voltage-Supply (Vcc/Vdd) range of 10V~30V. This component does not feature a Synchronous Rectifier, but has a high Duty Cycle (Max) of 97%, making it an efficient choice for various applications.
