LSN10A-D12

LSN-10A D12 Models Single Output, Non-Isolated, 12VIN, 1-5VOUT, 10A, DC/DC's in SIP Packages Features Step-down buck regulators for new distributed 12V power architectures 12V input (10.8-13.2V range) 1 to 5VOUT @ 10A Non-isolated, fixed-frequency, synchronous-rectifier topology Outstanding performance: ±1.25% setpoint accuracy Efficiencies to 96% @ 10 Amps Noise as low as 30mVp-p Stable no-load operation Trimmable output voltage Remote on/off control Sense pin on standard models Thermal shutdown No derating to +68°C with 100 lfm UL/IEC/EN60950 certified EMC compliant +INPUT (7,8) 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, stepdown 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. LSN D12's are ideal point-of-use/load power processors. They typically require no external components. Their vertical-mount packages occupy a mere 0.7 square inches (4.5 sq. cm), and reversed pin vertical mount allows mounting to meet competitor's keep out area. Horizontalmount packages ("H" suffix) are only 0.34 inches (8.6mm) high. The LSN's best-in-class power density is achieved with a fully synchronous, fixed-frequency, buck topology that also delivers: high efficiency (96% for 5VOUT models), low noise (30 to 50mVp-p typ.), tight line/load regulation (±0.1%/±0.25% max.), quick step response (100μsec), stable no-load operation, and no output reverse conduction. The fully functional LSN’s feature output overcurrent detection, continuous short-circuit protection, an output-voltage trim function, a remote on/off control pin (pull high to disable), thermal shutdown and a sense pin. High efficiency enables the LSN D12's to deliver rated output currents of 10 Amps at ambient temperatures to +68°C with 100 lfm air flow. If your new system boards call for three or more supply voltages, check out the economics of on-board 12V distributed power. If you don't need to pay for multiple isolation barriers, DATEL's non-isolated LSN D12 SIP's will save you money. +OUTPUT (1,2,4) 10.5 66μF 100μF 330μF +SENSE (3) COMMON (5) COMMON (6) CURRENT SENSE VCC ON/OFF CONTROL (11) 　 PWM CONTROLLER REFERENCE & ERROR AMP For devices with the sense-pin removed ("B" suffix), the feedback path is through the +Output pin and not the +Sense pin.

All models are tested and specified with external 22μF tantalum input and output capacitors. The capacitors are necessary to accommodate our test equipment and may not be required to achieve specified performance in your applications. See I/O Filtering and Noise Reduction. Ripple/Noise (R/N) is tested/specified over a 20MHz bandwidth and may be reduced with external filtering. See I/O Filtering and Noise Reduction for details. PART NUMBER STRUCTURE These devices have no minimum-load requirements and will regulate under no-load conditions. Regulation specifications describe the output-voltage deviation as the line voltage or load is varied from its nominal/midpoint value to either extreme. Nominal line voltage, no-load/full-load conditions. These are not complete model numbers. Please refer to the Part Number Structure when ordering.
