The MIC28513-1YFL-TR is a synchronous step-down switching regulator designed to operate within a wide input voltage range of 4.6V to 45V, providing up to 4A output current. It features integrated high-side and low-side N-channel MOSFETs, which enhance efficiency and reduce component count. The output voltage is adjustable down to 0.8V with a guaranteed accuracy of ¬±1%. The device supports a programmable switching frequency from 200 kHz to 680 kHz, allowing for flexibility in design. This regulator incorporates several protection features, including undervoltage lockout, thermal shutdown, and a foldback current limit with "hiccup" mode short-circuit protection. It also includes a built-in 5V regulator for single-supply operation and has a fixed soft-start time of 5 ms to minimize inrush current. The MIC28513-1 is housed in a thermally-enhanced 24-pin 3 mm x 4 mm FQFN package, suitable for applications requiring high efficiency and reliability, such as industrial power supplies and distributed supply regulation. The operational temperature range is from -40¬8C to +125¬8C, making it suitable for a variety of environments.
