Linear Technology LTC1174 Step-Down and Inverting DC/DC Converter Datasheet
The LTC1174 family provides high‑efficiency step‑down and inverting conversion for voltages from 4 V up to 18.5 V. It features a simple current‑mode architecture, an internal 0.9 µA switch, and requires only four external components, making it ideal for battery‑powered designs. The device includes built‑in short‑circuit protection, a low‑battery detector, and a micropower shutdown mode that reduces quiescent current to 1 pA.
Typical applications include portable instruments, battery chargers, and distributed power systems. The datasheet details pin functions, electrical characteristics, typical performance curves, and guidelines for inductor and diode selection to optimize efficiency and ripple current.
