Description
BD9001F-E2 is a DC-DC converter IC in ROHM’s BD9001F family. It’s a compact, high‑efficiency synchronous buck regulator designed to convert a higher input voltage to a stable lower output for microcontroller and peripheral rails.
Key points:
- Integrated high‑ and low‑side MOSFETs (no external FETs required).
- Wide input range with adjustable output via an external feedback divider.
- PWM/current‑mode control with soft‑start; enable pin available.
- Protections: overcurrent/short‑circuit, overvoltage/undervoltage, thermal shutdown.
- Commonly used to power MCUs, memory, and sensors in automotive, industrial, and consumer electronics.
- Available in small packages suitable for compact board layouts.
For exact pinout and electrical specs (VIN, VOUT, switching frequency, efficiency) and recommended circuits, consult the official ROHM BD9001F‑E2 datasheet.
