The MIC28512-1YFL-T5 is a synchronous step-down switching regulator designed to operate within a wide input voltage range of 4.6V to 70V, providing up to 2A output current. It features integrated high-side and low-side N-channel MOSFETs, allowing for efficient power conversion. 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, enhancing design flexibility. Key protective features include undervoltage lockout, internal soft-start to minimize inrush current, foldback current-limit, "hiccup" mode short-circuit protection, and thermal shutdown. The MIC28512-1YFL-T5 is housed in a thermally-enhanced 24-pin 3 mm x 4 mm FCQFN package and operates over a junction temperature range of -40¬8C to +125¬8C. This regulator is suitable for applications such as industrial power supplies, distributed supply regulation, and high-voltage single-board systems.
