The E-L4978D is a step-down switching regulator capable of delivering up to 2A with an adjustable output voltage ranging from 3.3V to 50V. It operates with an input voltage range of 8V to 55V and features a maximum switching frequency of 300KHz. The device incorporates several protection mechanisms, including pulse-by-pulse current limiting, hiccup mode for short circuit protection, thermal shutdown, and feedback loop disconnection protection. It also supports zero load current operation and includes a soft-start function to manage inrush current. The E-L4978D is available in a SO16W package suitable for surface mount assembly, making it versatile for various applications.
