The LM26400YSDX is a state-of-the-art dual output synchronous step-down DC/DC converter designed and manufactured by Texas Instruments. It is a highly integrated and efficient solution for applications requiring a compact, high-performance power supply. The device is capable of delivering up to 2A of continuous current per channel, making it suitable for powering core voltages, I/Os, and other system peripherals.

Key Features

• Dual Channel: Two independent 2A outputs with separate enable pins allow for versatile power management schemes.
• Wide Input Voltage Range: Operates from a 2.7V to 5.5V input, accommodating a variety of power sources including single-cell Li-ion batteries and 3.3V or 5V system rails.
• High Efficiency: Integrated synchronous MOSFETs enhance efficiency, reducing the need for external components and minimizing power loss.
• Adjustable Switching Frequency: Users can set the switching frequency from 500kHz to 4MHz, optimizing efficiency and component size.
• Power Save Mode: At light loads, the device automatically enters power save mode, reducing quiescent current and maintaining high efficiency over the entire load range.
• Thermal Protection: Built-in thermal shutdown and over-temperature protection safeguard the device from damage due to overheating.

Applications

The LM26400YSDX is ideal for a broad range of applications, including but not limited to:

• Portable and battery-powered devices
• Networking and telecommunications equipment
• Industrial and automotive systems
• Point-of-load power supplies
