LTC3407AIMSE-2

LTC3407AIMSE-2 Description

The LTC3407AIMSE-2 from Analog Devices Inc. is a dual-output, high-efficiency synchronous buck regulator designed for compact, power-sensitive applications. This obsolete model features two adjustable outputs delivering up to 800mA each, with an input voltage range of 2.5V to 5.5V and output voltages adjustable from 0.6V to 5V. Its 2.25MHz switching frequency enables the use of small external components, making it ideal for space-constrained designs. Packaged in a 10-pin MSOP tube, the device is surface-mountable and rated for MSL 1 (unlimited) moisture sensitivity, ensuring reliability in manufacturing.

LTC3407AIMSE-2 Features

• Dual-output buck regulator with synchronous rectification for high efficiency (up to 95%).
• Adjustable outputs (0.6V–5V) with 800mA current capacity per channel, suitable for multi-rail systems.
• Wide input range (2.5V–5.5V), compatible with Li-ion, USB, or 3.3V/5V supplies.
• 2.25MHz fixed-frequency operation minimizes inductor/capacitor size, reducing PCB footprint.
• Low dropout operation and automatic Burst Mode® for improved light-load efficiency.
• Compact 10MSOP package with surface-mount compatibility, ideal for portable electronics.

LTC3407AIMSE-2 Applications

• Portable devices: Smartphones, tablets, and wearables requiring dual low-noise rails.
• Distributed power systems: Point-of-load regulation for FPGAs, ASICs, or processors.
• Battery-powered equipment: Efficient power management in IoT sensors or handheld instruments.
• Industrial electronics: Space-constrained applications like embedded controllers or motor drivers.

Conclusion of LTC3407AIMSE-2

The LTC3407AIMSE-2 excels in high-density, multi-rail power designs with its synchronous rectification, adjustable outputs, and ultra-compact form factor. While obsolete, its high efficiency, fast switching, and robust performance make it a legacy solution for engineers optimizing space and power in portable or embedded systems. For modern alternatives, consider Analog Devices' newer buck regulators with enhanced features like lower quiescent current or wider input ranges.
