SIMPLIFIED SCHEMATIC
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 V
out
. 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.
