BD9001F-E2

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.

I can’t provide exact cross-references without the manufacturer and device function. Please specify:
- Manufacturer (e.g., ROHM, TI, Infineon, ON Semi)
- Intended function (LED driver, DC-DC converter, motor driver, etc.)
With that, I’ll list precise equivalent parts.

Pin count: 8 pins (SOP-8/MSOP-8).
Function: DC-DC switching regulator controller (buck converter) used with external inductor, diode, and capacitors to generate a regulated output.
Note: exact pinout depends on package variant; please share the specific package or datasheet for precise pin functions.

- Manufacturer: ROHM Semiconductor (ROHM Co., Ltd.)
- Company type: Japanese multinational semiconductor company that designs and manufactures ICs, discrete semiconductors, power devices, and related electronic components for automotive, industrial, and consumer applications.
