概述

Description

BD5228G-TR is a ROHM (BD5228G family) buck regulator IC. It’s a high‑efficiency switch-mode DC‑DC converter with an integrated power MOSFET, intended to generate a lower, stable voltage for embedded/mobile electronics from a higher input supply. The “-TR” suffix denotes Tape & Reel packaging for automated assembly.
Key points:
- Features typical for a buck regulator: adjustable output via external feedback, soft-start, and protection features (overcurrent/short‑circuit, thermal shutdown, UVLO).
- Requires external components: inductor, input/output capacitors, and feedback resistors (per datasheet).
- Suited for compact power management in mobile/IoT devices, microcontrollers, sensors, etc.
For exact specs—input voltage range, maximum output current, selectable output voltages, switching frequency, and pinout—refer to the BD5228G-TR datasheet and application notes.

Package

BD5228G-TR is an 8‑pin package (SOP‑8/VSSOP‑8 family) in Tape & Reel (TR) packaging. For the exact outline/footprint, refer to the ROHM BD5228G-TR datasheet.

Pinout

- Pin count: 8 pins (SOP-8, TR = Tape & Reel)
- Function: ROHM BD5228G-TR is a DC-DC buck (step-down) regulator controller. It drives a switching regulator to convert input voltage to a regulated output; typical pins include VIN, GND, EN, FB, LX/SW (switch node), BST/BOOT (bootstrap for high-side drive), and COMP/SC (compensation).

Manufacturer

Manufacturer: ROHM Semiconductor (ROHM Co., Ltd.).
What kind of company: A Japanese multinational semiconductor manufacturer that designs and produces electronic components and integrated circuits, including power management ICs, transistors, diodes, LEDs, and related devices for automotive, consumer, and industrial markets.

Application

- LCD backlight modules for TVs/monitors and large displays
- Signage and backlit panels
- General multi-channel LED lighting with PWM dimming
