... DATEL's LSM D5 Series for SMT (surface-mount) are non-isolated DC/ DC converters that accept a 5V input (4.5V to 5.5V input range) and deliver 0.8V, 1V, 1.2V, 1.5V, 1.8V, 2V, 2.5V, or 3.3V outputs at 10 Amps. LSM D5 SMT's are designed to take on-board 5V power and convert it, with the highest efficiency in the smallest space, to any lower voltage required by today's current-hungry DSP's, ASIC's and CPLD's ...

All models are tested and specified with external 22μF tantalum input and output capacitors. These 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/specifi ...

... See Typical Performance Curves. Remote Sense LSM D5 SMT Series DC/DC converters offer an output sense function on pin 6. The sense function enables point-of-use regulation for overcoming moderate IR drops in conductors and/or cabling. Since these are non-isolated devices whose inputs and outputs usually share the same ground plane, sense is provided only for the +Output ...

... If the output current exceeds it maximum rating by typically 70% (17 Amps the output voltage drops to less than 98 original value, the LSM D5's internal overcurrent-detection circuitry immediately turns off the converter, which then goes into a "hiccup" mode. While hiccupping, the converter will continuously attempt to restart itself, go into overcurrent, and then shut down ...
