LTC3546EUFD#TRPBF

LTC3546EUFD#TRPBF Description

The LTC3546EUFD#TRPBF from Analog Devices Inc. is a high-efficiency, dual-output synchronous buck regulator designed for compact, power-sensitive applications. This 2.25MHz/750kHz–4MHz switching regulator delivers adjustable outputs (0.6V to 5V) with 1A and 2A current capabilities, making it ideal for distributed power systems. Its 2.3V to 5.5V input range supports operation from Li-ion batteries or low-voltage rails, while the synchronous rectification ensures high efficiency (up to 95%) and reduced heat dissipation. Packaged in a 28-pin QFN with tape-and-reel (TR) delivery, it meets ROHS3 and REACH compliance, suitable for industrial and consumer electronics.

LTC3546EUFD#TRPBF Features

• Dual Independent Outputs: Configurable as 1A + 2A or dual 1A outputs for flexible power management.
• High Switching Frequency: 2.25MHz/750kHz–4MHz operation minimizes external component size (e.g., inductors, capacitors).
• Wide Input Range: 2.3V–5.5V accommodates diverse power sources, including single-cell batteries.
• Synchronous Operation: Integrated MOSFETs and >90% efficiency reduce power losses.
• Compact Design: 28-QFN package (4mm × 5mm) with MSL1 rating ensures reliability in space-constrained PCBs.
• Adjustable Outputs: 0.6V–5V range supports low-voltage processors (FPGAs, ASICs) and peripherals.

LTC3546EUFD#TRPBF Applications

• Portable Electronics: Smartphones, tablets, and wearables requiring dual-rail power from single-cell batteries.
• IoT Devices: Sensor nodes and wireless modules benefiting from high efficiency and small footprint.
• Industrial Systems: Distributed power for FPGAs, microcontrollers, and analog circuits in automation.
• Medical Devices: Battery-powered equipment where low noise and compact size are critical.
