Description
E-UC3845BN Overview
The part status of this particular electronic component is listed as obsolete, indicating that it is no longer being manufactured. However, for those who still have this component in their inventory, it is important to note the operating temperature range of 0°C~70°C TA. This means that the component can safely operate within this temperature range without any risk of damage. Additionally, the moisture sensitivity level (MSL) is 1 (unlimited), meaning that it can be exposed to unlimited moisture without any negative effects. With 8 pins and 1 output, this component is designed for single switcher configuration and has a maximum duty cycle of 50%. Its control features include frequency control and a rise time of 50ns. It also operates at a maximum supply voltage of 30V.
