概要

Description

Introduction (concise):
- LMR23630QDRRRQ1 is TI’s LMR family 3-A synchronous buck DC-DC regulator (Simple Switcher), intended to convert a higher input voltage to a stable lower output.
-Wide input range and efficiency: typically supports up to around 36 V input with adjustable output via an external resistor network; designed for automotive, industrial, and other power rails.
-Top features: integrated high- and low-side MOSFETs, enable/shutdown, overcurrent/overload protection, over-temperature protection, undervoltage lockout, and soft-start. It is optimized for good efficiency,including light-load operation.
- Package note: the “QDRRRQ1” suffix denotes the specific TI package/reel/ RoHS options (i.e., a particular packaging variant of LMR23630).
- Typical use: powering CPUs/SoCs, FPGA cores, and other 3-A class loads from 6–36 V automotive or industrial systems.
- Resources: TI product page, datasheet, and evaluation boards provide pinout, electrical specs, and application guidance.

Features

Key features of LMR23630QDRRRQ1:
- 3-A step-down DC-DC converter with integrated high-side MOSFET
- Wide input range: 4.5 V to 36 V
- Output voltage adjustable via external feedback (0.8 V reference); supports fixed options
- Switching frequency ~2.25 MHz
- Current-mode control with cycle-by-cycle current limiting
- High efficiency and compact solution
- Enable/shutdown pin; soft-start; undervoltage lockout
- Protections: overcurrent, thermal shutdown, short-circuit protection
- Small QFN package with exposed pad (RoHS compliant)

Package

LMR23630QDRRRQ1 uses TI’s DRRR package: a VQFN-16 (4×4 mm) leadless package (automotive Q1).

Pinout

- Pin count: 16 pins in a QFN-16 package (with an exposed pad).
- Function: LMR23630QDRRRQ1 is a high-efficiency 3-A step-down (buck) regulator. It accepts a relatively high input (up to about 42 V) and outputs a programmable lower voltage. It includes an internal high-side switch and requires external components (inductor and catch diode or synchronous rectifier). Key pins typically include VIN, EN/UVLO, LX (switch node), FB (feedback), COMP (external compensation), BST/BOOT (bootstrap for gate drive), GND/PGND, IS/ILIM (current limit sense), and an exposed pad for thermal grounding.

Manufacturer

Manufacturer: Texas Instruments (TI).
What kind of company: TI is an American multinational semiconductor company that designs and manufactures analog and embedded processing chips, power-management ICs (including buck regulators like the LMR23630), microcontrollers, and related development tools and reference designs for industrial, automotive, consumer and communications markets. Headquarters: Dallas, Texas; publicly traded.

Application

- Automotive-grade power conversion: ECUs, infotainment, ADAS, body electronics (9–42 V input, high-current 30 A outputs)
- Industrial and robotics: motor drives, PLCs, automation controllers, high‑current DC‑DC rails
- Networking/telecom: high‑current VRMs for switches, routers, telecom equipment
- General embedded power: high‑current DC‑DC conversion to 3.3 V/5 V rails in demanding systems
