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 applications 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 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
control, two additional ground pins (optional)
and a load Sense input. These converters meet
agency standards UL/EN 60950-1, CAN/CSA-
C22.2 60950-1, IEC 60950-1, 2nd edition, and
EN55022/CISPR22 emissions characterization.
The automated surface mount assembly is fully
compatible with RoHS (Reduction of Hazard-
ous Substances) 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.
