The SLDN-12D1A series power modules are non-isolated dc-dc converters that can deliver up to 12 A of output current. These modules operate over a wide range of input voltage (3 - 14.4 VDC) and provide a precisely regulated output voltage from 0.45 to 5.5 VDC, programmable via an external resistor and power management bus control. Features include a digital interface using the power management bus protocol, remote On/Off, adjustable output voltage, over current and over temperature protection. The power management bus interface supports a range of commands to both control and monitor the module. TM The modules also include the Tunable Loop feature that allows the user to optimize the dynamic response of the converter to match the load with reduced amount of output capacitance leading to savings on cost and PWB area. 3 - 14.4 VDC Input 0.45 - 5.5 VDC 12 A Output Wide Input Voltage Range Fixed Switching Frequency Power Good Signal Remote On/Off Digital interface through the Power Management Bus Protocol Ability to Sink and Source Current Cost Efficient Open Frame Design Over Temperature Protection TM Tunable Loop (a Registered Trademark of Lineage Power Systems) to Optimize Dynamic Output Voltage Response Flexible Output Voltage Sequencing EZ-SEQUENCE Output Over Current Protection (non-latching) Wide Operating Temperature Range -40C to 85C Class II, Category 2, Non-Isolated DC/DC Converter (refer to IPC-9592A) Compliant to RoHS EU Directive 2002/95/EC Compatible in a Pb-free or SnPb Reflow Environment Certificated to UL60950-1/CSA C22.2 No.60950-1, 2nd Distributed Power Architectures Intermediate Bus Voltage Applications Telecommunications Equipment Servers and Storage Applications Networking Equipment Industrial Equipment 2 SLDN-12D1A MODEL OUTPUT INPUT MAX.
