The LT8610ABEMSE is a compact, high-efficiency, synchronous monolithic step-down switching regulator from Linear Technology that delivers up to 2.5A of continuous output current. It operates over a wide input voltage range of 3.4V to 42V, making it suitable for applications with input sources ranging from single-cell Li-Ion batteries to automotive inputs.

Key Features

• High Efficiency: The LT8610ABEMSE features a high efficiency of up to 96%, which minimizes heat generation and allows for a smaller footprint on the PCB.
• Low Dropout Operation: Its low minimum on-time of just 30ns enables low dropout operation, making it ideal for automotive cold-crank and stop-start systems where the input voltage can sag below the regulated output voltage.
• Adjustable Frequency: With an adjustable and synchronizable switching frequency from 200kHz to 2.2MHz, the LT8610ABEMSE provides flexibility in optimizing inductor size and efficiency.
• Fast Minimum On-Time: The fast minimum on-time allows for high step-down ratio power conversion at high frequency with a small solution footprint.
• Thermal Performance: The LT8610ABEMSE comes in a thermally efficient 16-lead MSOP package with enhanced high voltage pin spacing, which is ideal for thermally demanding environments.

Applications

• Automotive and industrial power supplies
• General purpose step-down applications
• Point of load power conversion
• Distributed power systems

The LT8610ABEMSE also includes features such as internal compensation, a power good flag, output soft-start/tracking, and thermal protection. Its internal top and bottom synchronous power switches improve efficiency and eliminate the need for an external Schottky diode. This makes the LT8610ABEMSE a highly integrated solution that simplifies design and accelerates time to market for a wide range of applications.
