Linear Technology LT3430 Datasheet
The LT3430 is a constant‑frequency, current‑mode buck converter that operates from 5.5 V to 60 V input and delivers up to 3 A of output current. It features a 200 kHz switching frequency, low shutdown current (30 pA), and a 1.2 V feedback reference voltage, making it suitable for high‑efficiency power‑supply designs.
Typical applications include industrial and automotive power supplies, portable computers, battery chargers, and distributed power systems. The datasheet provides absolute maximum ratings, electrical characteristics, pin descriptions, block diagram, and layout recommendations for the 16‑lead TSSOP package.
