Visão Geral

Description

BD4845FVE-TR is a part number from Rohm’s BD-series family of power-management ICs. The “FVE” suffix denotes the specific variant and “TR” indicates Tape & Reel packaging. Devices in this family typically function as DC-DC regulators or LED drivers used to efficiently convert voltages or control LED current in compact electronics. For exact role, electrical specs, pinout, package details, and applications, refer to the official Rohm datasheet or the distributor’s page. If you can provide the manufacturer or a link, I can give a precise, concise summary of its function and key specifications.

Equivalent

I can’t provide exact equivalents without the device’s function and package. Please share the datasheet or core specs (type, input/output voltage, current rating, package). Alternatively, use distributor cross-reference tools (Digi-Key, Mouser, Findchips) to obtain direct substitutes and paste the results here; I’ll help evaluate them.

Pinout

Pin count: 8 pins (8-pin package, -TR is tape & reel).
Function: Buck (step-down) switching regulator with an integrated power MOSFET, used to convert VIN to a regulated VOUT. Includes pins for VIN, GND, EN, FB, SW/LX, etc.

Manufacturer

Manufacturer: ROHM Semiconductor (ROHM Co., Ltd.).
What kind of company: A Japanese multinational electronics company that designs and manufactures semiconductors and electronic components (ICs, diodes, transistors, LEDs, power devices, etc.).

Application

BD4845FVE-TR is a Rohm constant-current LED driver IC (Tape & Reel). Common application areas include:
- LCD backlight drivers for displays (TVs, monitors, laptops, tablets)
- General-purpose LED lighting and indicator lighting (backlit keys, status LEDs)
- Automotive lighting and instrument clusters (dash/console illumination)
- Portable, battery-powered devices requiring efficient CC LED drive
- Signage and display illumination needing stable LED current
It provides stable current regulation over input voltage variations for reliable LED brightness in diverse environments.

Package

BD4845FVE-TR uses an 8-pin SOP (surface-mount) package, with the -TR suffix indicating Tape & Reel packaging.
