概述

Description

BD9001F-E2 is a ROHM power-management IC (BD9001F family) used as a high‑efficiency DC‑DC buck regulator/LED driver. It functions as a switching regulator that converts a higher input voltage to a stable lower output. Depending on variant, it may include an integrated FET or require an external FET, and it typically needs external inductor, diode (or synchronous rectification), and a feedback network to set Vout. Key features usually include wide input range, soft-start, enable control, and protections such as undervoltage lockout, overcurrent/short‑circuit protection, and overtemperature shutdown. Package options vary by version (e.g., SOP-8, QFN). Common applications: automotive/industrial power supplies, LED backlighting, and compact DC‑DC power stages. For exact specs, pinout, and application circuits, consult the official datasheet for your specific revision.
