概要

Description

The LTC3630AIDHC#TRPBF is Linear Technology/Analog Devices’ high‑voltage, synchronous buck DC‑DC regulator with integrated MOSFETs. It provides efficient step‑down conversion from a wide input range (up to about 60V) to a lower output voltage set by an external feedback network. The device uses fixed‑frequency, current‑mode PWM, includes soft‑start, an enable/shutdown pin, and protections such as overcurrent, thermal shutdown, and undervoltage lockout. It requires an external inductor, input/output capacitors, and a feedback divider to complete the regulator. The AIDHC suffix denotes the specific 8‑pin package, while #TRPBF indicates Tape‑and‑Reel Pb‑free packaging. Typical applications include automotive and industrial power supplies, battery-powered systems, and other environments requiring robust, high‑voltage DC conversion. For exact electrical specs, pinout, and implementation details, refer to the LTC3630A datasheet.

Features

Key features of LTC3630AIDHC#TRPBF (compact 3A step-down regulator in TRPBF package):
- 3A switch current with integrated high-side/low-side MOSFETs (synchronous buck)
- Adjustable output via external feedback network
- Current-mode control for fast transient response
- Fixed-frequency PWM operation (with possible PWM/PFM modes)
- Soft-start to limit inrush and prevent output surge
- Enable input and power-good/status signaling
- Robust protection: overcurrent/short-circuit, overvoltage, undervoltage lockout, and thermal shutdown
- High efficiency from synchronous rectification
- Suitable for ceramic-capacitor outputs; compact TRPBF packaging
Note: Exact voltage ranges, optional modes, and packaging details are in the official datasheet.

Package

LTC3630AIDHC#TRPBF is supplied in a 12‑lead DFN package (DHC). It is RoHS/Pb‑free and shipped tape‑and‑reel (TRPBF). The "I" denotes industrial temperature grade.

Pinout

Pin count: 10 pins.
Function: LTC3630AIDHC is a synchronous step‑down (buck) switching regulator IC in Linear/Analog Devices' 10‑lead DHC (3 mm × 3 mm DFN) package. It integrates the power MOSFETs and control circuitry to convert a higher input voltage to an adjustable lower output voltage with high efficiency. Suffix #TRPBF denotes tape‑and‑reel packaging and Pb‑free (RoHS) finish.

Manufacturer

The LTC3630AIDHC#TRPBF is manufactured by Analog Devices (originally Linear Technology — the LTC brand). Analog Devices is a semiconductor company that designs and manufactures analog, mixed-signal, and power-management integrated circuits, specializing in products such as voltage regulators, data converters, amplifiers, and other ICs for industrial, communications, and consumer applications.

Application

Applications: High-current VRMs and point-of-load regulators using a multi-phase buck topology. Suitable for delivering CPU/GPU/FPGA/ASIC rails; power modules in servers, data centers, and AI accelerators; telecom/network equipment; graphics cards and other high-performance compute boards; industrial control systems and high-reliability power supplies.

Equivalent

Direct equivalents are the same device with different ordering suffixes: LTC3630AIDHC (base), LTC3630AIDHC#TRPBF (tape & reel, RoHS), LTC3630AIDHC#PBF (Pb‑free). These are the drop‑in/ordering variants of the LTC3630A family; there is no guaranteed cross‑manufacturer drop‑in — contact Analog Devices for recommended substitutes.
