Description

UC2845ADTR Overview
The package or case of this electronic component is a 14-SOIC with a width of 0.154 inches or 3.90mm. It requires a supply voltage of 11V and has a step-up function, meaning it can increase the input voltage to a higher output voltage. It also has the capability of both step-up and step-down functions. This component has one output and a maximum supply current of 25mA. Its fall time, which is the time it takes for the output to decrease from a high to low state, is 50 ns. The nominal input voltage for this component is 25V and it is configured as a BUCK-BOOST switcher. With a height of 1.75mm and a width of 3.91mm, this component is compact and versatile for various electronic applications.
