DESCRIPTION
Today’s high performance CPU and programma-
ble logic devices demand superior performance
from their power source. The LSM2-T/30-D12
series DC/DC converters offer up to 30 Amps
continuous output power with a user-selectable
output of 0.8 to 3.6 Volts. 25 Amps output is
available up to 5.0 VOUT. This tiny converter is
ideal for distributed bus architectures (DBA) and
intermediate power busses with an input range
of 6 to 14 Volts DC. The pinout, trim system and
mechanical footprint is compatible with the DOSA
(www.dosapower.com) industry standard.
To ensure very high performance of powered
logic systems, the LSM2-T/30-D12 features low
output noise, high slew rates (20 Amps/μSec.),
fast transient response (25 μSec settling) and
tight line and load regulation. Many logic devices
require controlled start up and tracking capabili-
ties. The LSM2-T/30-D12 includes a Sequence/
Track function and prebias protection against
external startup voltages. Other DBA features
include no additional external components
required, stable no-load operation, up to 10,000
μF output load capacitance and no reverse
conduction.
System functions offer a remote On/Off con-
trol, two additional ground pins (optional) and a
load Sense input. Agency certifications include
UL/EN 60950-1, CAN/CSA-C22.2 60950-1, IEC
60950-1, and FCC emissions characterization.
The automated surface mount assembly is fully
RoHS (Reduction of Hazardous Substances)
lead-free construction and attachment. The
LSM2-T/30-D12 mounts to its host carrier
board via reflow-soldered PCB pads.
The extraordinary efficiency means low heat
and freedom from expensive, bulky heat sinks. A
wealth of protection features include input under-
voltage shutdown, output overcurrent current lim-
iting, short circuit protection and overtemperature
shutdown/recycle.
