DOSA-SMT, 30A POL DC/DC Converters
Typical unit
FEATURES
DESCRIPTION
Non-isolated Point-of-Load (POL) converter, ideal
for mixed voltage systems
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
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.
Optimized for CPUs, DSPs and programmable logic
- FPGAs, ASICs
30 Amps maximum output current
User-selectable output voltage, 0.8Vdc to 5.0Vdc
via trim resistor or voltage input
Wide input range 6Vdc to 14Vdc (Vout <3.6V)
Selectable phased start-up sequencing and tracking
mechanical footprint is compatible with the DOSA The automated surface mount assembly is fully
(www.dosapower.com) industry standard.
Excellent efficiency over output voltage range
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.
Two models available, with or without additional
ground/thermal pads
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
Fast settling, high di/dt slew rate, low output noise
Extensive self protection plus 'hiccup' short circuit
auto recovery
Meets full safety and emission certification
