概述

Description

Introduction to LTC3536IDD#TRPBF
- What it is: A dual synchronous DC‑DC regulator from Analog Devices (formerly Linear Technology) that houses two power regulators on a single device to generate two regulated rails from one input source.
- How it works: Uses high‑efficiency synchronous switching with external feedback networks to set output voltages; supports enable control and soft‑start; includes protection features (e.g., current limit, thermal shutdown).
- Packaging: The suffix IDD refers to the device/package variant; #TRPBF indicates Tape‑and‑Reel Pb‑free packaging.
- Applications: Portable/battery‑powered electronics and PMICs needing two regulated rails with high efficiency.
- Note: For exact electrical specs, pinout, and application examples, consult the LTC3536 datasheet and reference designs.

Features

Here are the key features of LTC3536IDD#TRPBF:
- Triple synchronous buck regulators with integrated high/low-side MOSFETs
- Input voltage range: 1.8V to 5.5V
- Adjustable outputs per channel (via resistor dividers)
- Independent enable/shutdown controls and soft-start
- High efficiency (>90% typical) with fast transient response
- Programmable switching frequency (often 400kHz–2MHz range)
- Current-mode control with external compensation
- Output voltage tracking/sequencing for multi-supply rails
- Remote sense for accurate regulation at the load
- Overcurrent/short-circuit protection and thermal shutdown
- Power-good/status indication and fault reporting
- Small Pb-free package in tape-and-reel (TRPBF variant)
Note: Exact voltage ranges, efficiency, and pinout depend on the specific datasheet revision.

Package

8-lead MSOP (MSOP-8) package, RoHS-compliant, tape-and-reel.

Pinout

- Pin count: 28 pins (28-pin package; TRPBF Pb-free, Tape & Reel).
- Function: Dual synchronous buck DC-DC converter. Two independent switching regulators share VIN and GND, each with its own LX switch node, FB, and EN. Outputs are VOUTA and VOUTB, with typical protection features (current limit, thermal/OV protection) and soft-start.

Manufacturer

- Manufacturer: Analog Devices, Inc. (AD). The LTC prefix originally came from Linear Technology, which Analog Devices acquired in 2017, so the current maker is Analog Devices.
- Company type: A multinational American semiconductor company that designs and manufactures analog, mixed-signal, and related processing integrated circuits.

Application

Applications:
- Portable and battery-powered devices
- Automotive and industrial power systems
- Telecom and networking equipment
- Multi-rail power supplies for CPUs, memory, and peripherals
- Energy-harvesting/solar-powered systems
- General compact, high-efficiency DC-DC conversion from wide input ranges
