概述
Description
The LT3845AEFE is a high-performance, current-mode DC/DC controller from Analog Devices (Linear Technology). Designed for step-down (buck) applications, it operates over a wide input range (4V–60V) and delivers up to 20A output current with external MOSFETs.
Key features include:
- Efficiency: Synchronous rectification and low dropout operation.
- Protections: Overcurrent, overvoltage, and thermal shutdown.
- Adjustability: Programmable switching frequency (100kHz–1MHz) and soft-start.
- Package: 38-lead TSSOP with exposed pad for thermal management.
Ideal for industrial, automotive, and telecom systems requiring robust, high-power conversion. Its current-mode control ensures fast transient response and stable operation.
For detailed specs, refer to the datasheet.
