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

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.

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
