This datasheet provides detailed specifications for the C&D LSN-10A D5 Series SIP non-isolated DC/DC converters. These converters accept a 5V input (4.5V to 5.5V input range) and deliver 1V, 1.2V, 1.5V, 1.8V, 2V, 2.5, 3.3 or 3.8V outputs at 10 Amps.
The LSN-10A D5 series from C&D Technologies provides non‑isolated, fully synchronous buck converters in single‑in‑line (SIP) packages. They accept a 4.5‑5.5 V input and deliver selectable output voltages from 1 V to 3.8 V at up to 10 A, with efficiencies reaching 95 %.
These devices include features such as remote on/off control, output‑voltage trim, thermal shutdown, and over‑current protection. They are UL/IEC/EN60950 certified, RoHS compliant, and available in both vertical‑mount (0.34 in high) and horizontal‑mount (0.7 sq in) configurations.
