BD63536FJ is a high-frequency switching regulator produced by ROHM. It has a rated voltage of 3V and uses a SOP-J8 package. The regulator features a 1% reference voltage accuracy and a 4% overcurrent protection function, and has a variety of built-in protection circuits, which can be used in laser printers, multifunction printers and personal computers.
The BD63536FJ is a gate‑direct‑drive switching regulator designed for step‑down DC/DC conversion. It operates from a 3 V to 30 V supply and uses a compact SOP‑J8 package. The device includes built‑in current‑limit, soft‑start, thermal shutdown, and a 2.5 V reference output.
Key features include a +1 % reference voltage accuracy, external FET drive capability, and programmable oscillation frequency via an external resistor‑capacitor network. The note lists absolute maximum ratings, detailed electrical characteristics, pin descriptions, and recommended external components for stable operation.
