... See Typical Performance Curves. Remote Sense LSM D12 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 ...

... High-current-carrying components such as inductors, FET's and diodes are at the highest risk. LSM D12 SMT Series DC/DC converters incorporate an output overcurrent detection and shutdown function that serves to protect both the power converter and its load. ...

... If the output current exceeds it maximum rating by typically 70 the output voltage drops to less than 98 original value, the LSM D12's inter- nal overcurrent-detection circuitry immediately turns off the converter, which then goes into a "hiccup" mode. While hiccupping, the converter will continu- ously attempt to restart itself, go into overcurrent, and then shut down. Once the output short is removed, the converter will automatically restart itself. Output Voltage Trimming (Except " ...

... In both cases, the cause is the "freewheeling" or "catch" FET biasing itself on and effectively becoming a short circuit. LSM D12 SMT DC/DC converters do not suffer from Output Reverse Conduc- tion. They employ proprietary gate drive circuitry that makes them immune to applied output voltages ...

... We assemble our SMT DC/DC’ thermally-stable plastic lead-frame (nylon 46, UL94V-0 flammability rated) using a high temper- ature lead-free solder. In addition, the LSM is transitioning to RoHS (Reduction of Hazardous Substances) construction and SAC 305 RoHS-approved solder. The lead-frame ensures coplanarity (to within 0.004 in.) of the unit's copper leads ...
