Description

UCC2581D Overview
The product has 14 pins and a Moisture Sensitivity Level (MSL) of 2, which means it can be stored for up to 1 year before it needs to be reflowed. The base part number is UCC2581. It has an output voltage of 600mV and an operating supply current of 300μA. The control mode is voltage-mode, indicating that it regulates the output voltage based on the input voltage. The fall time is typically 20 ns, and the maximum duty cycle is 84%. It also has clock sync capabilities, allowing it to synchronize with an external clock signal. Lastly, it is RoHS3 compliant, meaning it meets the requirements of the Restriction of Hazardous Substances directive.
