MURATA POWER SOLUTIONS Single Output LSN-10A D12 Models Features Non-Isolated 12VIN 1-5VOUT 10 Amp DC/DC s in SIP Packages
The LSN‑10A D12 series provides a single‑output, non‑isolated step‑down converter that accepts a 12 V input (10.8‑13.2 V range) and delivers selectable output voltages from 1 V to 5 V at a full‑load current of 10 A. The devices are offered in a compact 0.7 sq in (4.5 cm²) vertical‑mount SIP package, with an optional low‑profile horizontal‑mount version.
Key functional features include a fully synchronous fixed‑frequency buck topology, remote on/off control, output‑voltage trimming (±10 %), over‑current detection with hiccup shutdown, and thermal shutdown at +115 °C. The converters achieve up to 96 % efficiency (5 V model) and exhibit low output noise of 30‑50 mVp‑p. This manual is written in Chinese.
