LS2405IDD23 5A Synchronous Step-Down Buck Converter (2.7-24V)

Power your most demanding electronic payloads safely and efficiently with the LS2405IDD23 synchronous step-down converter. When designing custom robotics, heavy-lift drones, or advanced lighting systems, standard regulators simply cannot handle the heat and current requirements. This high-performance IC is built for heavy lifting, delivering a massive 5A of continuous output current. It is the perfect backbone for custom Battery Eliminator Circuits (BECs) designed to power hungry companion computers (like the Raspberry Pi 4/5), multiple high-torque digital servos, or high-power VTX modules.

Operating seamlessly on an input range of 2.7V to 24V, it is perfectly matched for 3S, 4S, and 5S LiPo battery configurations. Thanks to its synchronous rectification topology, it achieves exceptional power conversion efficiency, drastically reducing thermal dissipation compared to traditional buck converters. This allows you to draw high current without requiring massive aluminum heatsinks, keeping your custom Power Distribution Boards (PDBs) lightweight and compact.

Key Features:

• Massive 5A Output: Safely drives high-current loads like onboard microcomputers, servo clusters, and high-wattage LED arrays without thermal throttling.

• Wide Input Voltage: The 2.7V to 24V range makes it highly versatile, easily stepping down voltage from 3S, 4S, and 5S LiPo battery packs.

• High Efficiency: Synchronous switching topology significantly reduces heat generation, protecting tightly packed electronics in enclosed spaces.

• Heavy-Duty BEC Core: The ultimate IC for designing custom step-down modules that require uncompromising reliability under heavy load.
