Texas Instruments UC3843N

UC3843N Overview
The manufacturer of this component is Texas Instruments. It is a type of PMIC (power management integrated circuit) that falls under the category of voltage regulators and DC-DC switching controllers. It is not designed for surface mounting and is assigned the JESD-609 code of e4, indicating its compliance with industry standards. It is also lead-free, as indicated by its Pbfree code, and is currently unavailable as it is considered obsolete. Its moisture sensitivity level is 3, meaning it can withstand up to 168 hours of exposure to moisture. This chip has 8 termination points and is made using BICMOS technology. Its function is to regulate voltage by either stepping it up or stepping it down, and it has a single output. This output can handle a maximum current of 1A.
