LSN-10A D12 Models www.murata-ps.com Single Output, Non-Isolated, 12VIN, 1-5VOUT, 10A, DC/DC s in SIP Packages LSN Series D12 SIP s (single-in-line packages) are ideal building blocks for emerging, on-board power-distribution schemes in which isolated 12V buses deliver power to any number of non-isolated, step- down buck regulators. LSN D12 DC/DC s accept a 12V input (10.8V to 13.2V input range) and convert it, with the highest efficiency in the smallest space, to a 1, 1.1, 1.2, 1.3, 1.5, 1.8, 2, 2.5, 3.3 or 5 Volt output fully rated at 10 Amps. Features LSN D12 s are ideal point-of-use/load power processors. They typi- Step-down buck regulators for new cally require no external components. Their vertical-mount packages distributed 12V power architectures occupy a mere 0.7 square inches (4.5 sq. cm), and reversed pin vertical 12V input (10.8-13.2V range) mount allows mounting to meet competitor s keep out area. Horizontal- mount packages suffix) are only 0.34 inches (8.6mm) high. 1 to 5VOUT 10A The LSN s best-in-class power density is achieved with a fully Non-isolated, fixed-frequency, synchronous, fixed-frequency, buck topology that also delivers: high synchronous-rectifier topology efficiency (96% for 5V OUT models), low noise (30 to 50mVp-p typ.), Outstanding performance: tight line/load regulation (0.1%/0.25% max.), quick step response 1.25% setpoint accuracy (100sec), stable no-load operation, and no output reverse conduction. Efficiencies to 96% 10 Amps The fully functional LSNs feature output overcurrent detection, Noise as low as 30mVp-p continuous short-circuit protection, an output-voltage trim function, a remote on/off control pin (pull high to disable), thermal shutdown and a Stable no-load operation sense pin. High efficiency enables the LSN D12 s to deliver rated output Trimmable output voltage currents of 10 Amps at ambient temperatures to +68C with 100 lfm air Remote on/off control ofl w.
