Overview
Description
Key features include its synchronous rectification, which improves efficiency by minimizing power loss, and a fast transient response thanks to its high switching frequencies. The LT8650SEV#PBF supports Burst Mode® operation, reducing power consumption during light loads, which is advantageous for battery-powered applications.
The regulator's compact design is complemented by a thermally enhanced 28-lead TSSOP package, promoting efficient heat dissipation. The device also provides robust protection features, such as output short-circuit protection and thermal shutdown.
Overall, the LT8650SEV#PBF is ideal for applications requiring efficient, low-noise power conversion, such as automotive, industrial, and communications systems.
Features
1. Input Voltage Range: It operates from a wide input voltage range of 3V to 42V, suitable for automotive and industrial applications.
2. Output Current: Each channel delivers up to 4A of continuous output current.
3. Efficiency: High efficiency of up to 94% due to synchronous rectification and low quiescent current.
4. Switching Frequency: Offers a programmable switching frequency from 300kHz to 3MHz for optimizing efficiency and size.
5. Low IQ: Ultralow quiescent current of 6.2µA improves battery life in low-power systems.
6. Fast Transient Response: Adaptive On-Time architecture provides fast transient response.
7. Protection Features: Includes overcurrent, thermal shutdown, and short-circuit protection for reliability.
8. Package: Comes in a compact 32-lead 4mm x 6mm QFN package, facilitating space-constrained designs.
9. Soft-Start and Tracking: Programmable soft-start and tracking features for controlled startup.
10. Burst Mode Operation: Reduces power consumption during light-load conditions.
These features make the LT8650SEV#PBF suitable for efficient power conversion in applications like automotive systems, industrial power supplies, and battery-operated devices.
Package
Pinout
The LT8650SEV#PBF functions as a high-efficiency, monolithic, synchronous step-down regulator. It features dual channels, allowing it to step down two separate input voltages simultaneously. This makes it suitable for applications requiring multiple output voltage rails. The chip operates from an input voltage range of 3V to 42V and can deliver up to 4A of continuous output current per channel, making it ideal for automotive, industrial, and other high-performance applications. The device also includes features like fast transient response, low quiescent current, and high efficiency across a wide range of load conditions.
