Single Output LSN-W3 Models www.murata-ps.com Non-Isolated, 3-5.5VIN, 0.75-3.3VOUT 16 Amp DC/DC Converters NOT RECOMMENDED FOR NEW DESIGNS Typical unit FEATURES PRODUCT OVERVIEW „ Step-down, wide input buck regulators for distributed 3-5V power architectures „ 3V to 5.5V wide-input range LSN Series W3 are ideal building blocks for emerging, on-board power-distribution schemes in which isolated 3 to 5.5V buses deliver power to any number of non-isolated, step-down buck regulators. LSN W3 DC/DC’s accept 3 to 5.5 Volts and convert it, with the highest efficiency in the smallest space, to a 0.75, 1, 1.2, 1.5, 1.8, 2, 2.5, or 3.3 Volt output fully rated at 16 Amps. LSN W3’s are ideal point-of-use/load power processors. They typically require no external components. Their surface-mount packages occupy a mere 1.3" x 0.53" (33.0 x 13.5mm), and are only 0.34 inches (8.6mm) high. The LSN’s best-in-class power density is achieved with a fully synchronous, fixedfrequency, buck topology that also delivers: high efficiency (97%, 3.3Vout, 8A), low noise „ 0.75/1/1.2/1.5/1.8/2/2.5/3.3VOUT @16A „ Non-isolated, fixed-frequency, synchronous-rectifier topology „ ±1% setpoint accuracy „ Efficiencies to 95% @ 16 Amps „ Noise as low as 30mVp-p „ Stable no-load operation „ Remote on/off control „ Sense pin and output voltage trim „ No derating to +65°C with no fan „ UL/IEC/EN60950-1 certification pending (30mVp-p typ.), tight line/load regulation (±0.1%/±0.25% max.), quick step response (30μsec), stable no-load operation, and no output reverse conduction. The fully functional LSN’s feature output overcurrent detection, continuous short-circuit protection, over-temperature protection, a remote on/off control pin (pull low to disable), an output-voltage trim function, and a sense pin. High efficiency enables the LSN W3’s to deliver rated output currents of 16 Amps at ambient temperatures to +65°C with natural convection. If your new system boards call for multiple supply voltages, check out the economics of on-board 3-5.5V distributed power. If you don’t need to pay for multiple isolation barriers, DATEL’s non-isolated LSN W3 SMT’s will save you money. „ EMC compliant Typical topology is shown.
