These are indicated with the “R” designator in the model number, LSM2-T/30-D12R-C. MPS recommends that users lay out their PC boards to accept these two pads for larger current applications. Please note that the Derating curves for the “R” models accept higher temperature and greater current limits than units without the additional pads. 1 2 0 ANGLES: 1 22.02 0.867 1.22 0.048 26.85 1.057 29.90 1.177 Components are shown for reference only. 30.58 1.204 29.90 1.177 0.69 0.027 DIMENSIONS ARE IN INCHES [mm] TOLERANCES: 2 PLACE 0.02 3 PLACE 0.010 +Output 3.05 0.120 10 1.27 0.050 2.90 0.114 Common 5 Dimensions are in inches (mm) shown for ref. only. 9 2 4 ALL PINS COPLANAR WITHIN 4 MILS BOTTOM VIEW 5 Sequence/Track In * 8.76 0.345 4.83 0.190 REF 10.92 0.430 2.03±0.13 0.080±0.005 REF +Input 3 6 9.1 0.36 MTG PLANE On/Off Control 2 9 * 3 4 5 3.56 0.140 REF 6 7 2.41 0.095 REF 33.5 1.32 2.16 0.085 0 3.05 0.120 10.29 0.405 14.0 0.55 0.095 [2.41] x 0.082 [2.08] PADS FOR PINS 9 & 10 (OPTIONAL GNDS) To realize the additional current and thermal capacity of “R” models, you must have a substantial area of several square inches of copper etch flowsoldered to these pads and sufficient feed-throughs or other means of conducting current.

Exposure of devices to greater than any of these conditions may adversely affect long-term reliability. Proper operation under conditions other than those listed in the Performance/Functional Specifications Table is neither implied nor recommended. Specification Notes: (1) Specifications are typical at +25°C, Vin=nominal (+12V), Vout=nominal (+5V), full load, external caps and natural convection unless otherwise indicated. Tests at full power should supply substantial forced airflow. All models are tested and specified with external 0.1µF and 10 µF paralleled ceramic/tantalum output capacitors and a 22 µF external input capacitor. All capacitors are low ESR types. These capacitors are necessary to accommodate our test equipment and may not be required to achieve specified performance in your applications. All models are stable and regulate within spec under no-load conditions. (2) Input Back Ripple Current is tested and specified over a 5 Hz to 20 MHz bandwidth. Input filtering is Cin=2 x 100 µF tantalum, Cbus=1000 µF electrolytic, Lbus=1 µH. (3) Note that Maximum Power Derating curves indicate an average current at nominal input voltage. At higher temperatures and/or lower airflow, the DC/DC converter will tolerate brief full current outputs if the total RMS current over time does not exceed the Derating curve. (4) Mean Time Before Failure is calculated using the Telcordia (Belcore) SR-332 Method 1, Case 3, ground fixed conditions, Tpcboard=+25°C, full output load, natural air convection. (5) The On/Off Control may be driven with external logic or by applying appropriate external voltages which are referenced to -Input Common. The On/Off Control Input should use either an open collector/open drain transistor or logic gate which does not exceed +Vin. (6) Short circuit shutdown begins when the output voltage degrades approximately 2% from the selected setting. www.murata-ps.com/support MDC_LSM2_T30_D12 Series.E03∆ Page 5 of 12 LSM2-T/30-D12 Series DOSA-SMT, 30A POL DC/DC Converters Specification Notes continued: (7) If Sense is connected remotely at the load, up to 0.5 Volts difference is allowed between the Sense and +Vout pins to compensate for ohmic voltage drop in the power lines. A larger voltage drop may cause the converter to exceed maximum power dissipation. (8) Output noise may be further reduced by adding an external filter. See I/O Filtering and Noise Reduction. (9) All models are fully operational and meet published specifications, including “cold start” at –40° C. (10) Regulation specifications describe the deviation as the line input voltage or output load current is varied from a nominal midpoint value to either extreme. (11) Other input or output voltage ranges will be reviewed under scheduled quantity special order. (12) Maximum continuous power requires that all on-board components not exceed +128°C package temperature. (13) Do not exceed maximum power specifications when adjusting the output trim. (14) The “R” option includes extra ground pads. These pads offer two important features. In addition to carrying extra current, they also help dissipate additional heat. MPS strongly recommends soldering the “R” pads to a thick ground plane with sizable area. The Operating Temperature specification listed above assumes that these additional ground pads are connected to a substantial ground plane below the converter ( at least several square inches). (15) The maximum output capacitive loads depend on the the Equivalent Series Resistance (ESR) of the external output capacitor. Larger caps will reduce output noise but may slow transient response. (16) Do not use Pre-bias startup and sequencing together. If you do not use the track function, leave the seq/trk pin open. (17) After short circuit shutdown, if the load is partially removed such that the load still exceeds the overcurrent (OC) detection, the converter will remain in hiccup restart mode. (18) Output current limiting is disabled at start up to avoid overcurrent shutdown while charging external bypass capacitors.

The output voltage may be varied using a single trim resistor from the Trim Input to Power Common. Use a precision, low-tempco resistor (±100 ppm/οC) mounted close to the converter with short leads. Be aware that the voltage accuracy is ±1.5% (typical) therefore adjust this resistance to achieve your desired output. 2.90 KΩ 1.5V. 1.614 KΩ 5.0V. 185.71 Ω 1.8V. 1.10 KΩ Voltage Reference, Figure 2. Voltage Trim Connections Voltage Trim The LSM2 Series may also be trimmed using an external low-noise voltage applied between the Trim input and Output Common. Be aware that the internal “load” impedance looking into Trim pin is below 1000 Ohms and includes factors from the output voltage. Therefore, use a low impedance source resistance in your external voltage reference. The fixed trim voltages to set the output voltage are: Figure 1.
