Linear Technology LT1374 4.5A 500kHz Step-Down Switching Regulator Datasheet
The LT1374 is a constant‑frequency, current‑mode buck converter designed for portable computers, battery chargers and other distributed‑power applications. It integrates a 4.5 A switch, oscillator, control and logic circuitry in a monolithic package, offering high efficiency and a small external component size.
The device includes shutdown, synchronization and bias pins for power‑saving and performance tuning, and is offered in several surface‑mount packages such as 7‑lead TO‑220, 8‑lead plastic and 16‑lead TSSOP. Detailed electrical characteristics, pin functions and typical performance graphs are provided for designers.
