LSS-T/10-W12 www.murata-ps.com Adjustable Output 10 Amp SIP-mount DC/DC Converter PRODUCT OVERVIEW Fabricated on a Single Inline Package (SIP) module, stable no-load operation. A key feature is select- the LSS-T/10-W12 series is a miniature non-iso- able output voltage either by precision resistor, lated Point-of-Load (POL) switching DC/DC power trim pot or users voltage input. The output range is converter for embedded applications. The converter adjustable from 0.6 to 6 Vdc. offers both tight regulation and high efficiency A wealth of protection features prevents damage directly at the power usage site. Typically, no extra to both the converter and outside circuits. Inputs outside components are required. The module are protected from undervoltage and outputs offer mounts vertically, occupying a tiny board footprint. short circuit protection, overcurrent and excess The upright mounting improves cooling airflow. temperature shut down. The unit is designed to Suggested applications include powering CPUs, meet all EMI/RFI certifications as well as HALT distributed bus architectures (DBA) with a master reliability. RoHS6 hazardous material compliance bus power supply, programmable logic and mixed is specified as standard. All units are precision voltage systems. assembled in a highly automated computer- FEATURES Based on synchronous buck converter topology, controlled surface mount facility with ISO-traceable the extraordinary efficiency means very low heat manufacturing quality standards. Additional system n Vertical SIP-mount small footprint package and little electrical noise. The ultra wide input functions include a remote On/Off control. n Output from 0.6 to 6 Volts up to range is 4.5 to 13.8 Volts. Additional features 51 Watts include quick transient response to step loads and n Ultra-wide 4.5 to 13.8 Vdc input range n Outstanding thermal performance and derating n Extensive self-protection and short circuit features with no output reverse conduction n On/Off control and trim functions n High efficiency up to 93% with no heatsink n Fully protected against temperature and voltage limits n Designed to meet UL/IEC/EN60950-1 safety approvals Simplified Block Diagram +VIN +VOUT PWM On/Off Controller Control OT Common Common Signal Conditioning Trim Typical topology is shown.
