Vue d'ensemble

Description

The LT3990IDD#TRPBF is a high-performance, monolithic step-down switching regulator designed by Analog Devices, under the Linear Technology brand. It is intended for use in applications that require a compact, efficient power solution with minimal external components. The regulator operates over a wide input voltage range and delivers an adjustable output voltage, making it versatile for various power management needs.
Key features include a 3.3A output current capability, high efficiency over a broad load range, and a low quiescent current, which is beneficial for battery-powered applications. The device supports input voltages up to 60V and can regulate outputs as low as 0.8V. The LT3990 uses a 300kHz fixed-frequency PWM (Pulse Width Modulation) operation, providing a stable and reliable performance.
Moreover, it includes protection features such as cycle-by-cycle current limit, thermal shutdown, and output overvoltage protection, ensuring robust operation across different conditions. The LT3990IDD#TRPBF is housed in a thermally enhanced 10-lead Plastic DFN package, promoting effective heat dissipation. This makes it suitable for demanding environments where thermal performance and space efficiency are critical.
