Description

UC3842AD Overview
The mounting type for this particular component is surface mount, which means it can be easily attached to a circuit board. Its JESD-609 code is e4, indicating its level of sensitivity to electrostatic discharge. The Pbfree code is yes, meaning it is free from lead, a harmful substance. However, despite these positive features, the part status is obsolete, meaning it is no longer in production. It has 14 terminations, or connection points, and only one output. The output configuration is positive, and it requires a voltage supply of 10V to 30V. The switcher configuration is single, indicating that it can only perform one function. Lastly, the component is ROHS3 compliant, meaning it meets the standards for environmentally-friendly materials.
