Features

Designed to ease the evaluation of today's subminiature surface-mount technol-

ogy (SMT) 10 Amp single output DC/DC power converters, DATEL's LSM-EB

series includes twenty four models for all popular logic family output voltages and

common input power voltages. Each LSM-EB model consists of a 4.31-inch square

circuit board including a DATEL LSM-series surface mounted DC/DC converter,

input/output banana jacks, trim circuits and various passive components.

Rather than hand wiring to small mounting pads, the user can more accurately

test real world electrical and thermal performance on a mounting board with a full

ground plane and input Pi filter. The circuit board is mounted on four removable

one-inch standoffs threaded for 4-40 screw attachment.

The heart of the LSM-EB evaluation board is DATEL's advanced single output

non-isolated LSM series DC/DC converter. Running from either 3.3 Volt, 5 Volt or

12 Volt DC input power, the LSM series provides high quality point-of-load (POL)

output power for CPU's, memory systems, microcontrollers and large array logic.

See DATEL's LSM Series data sheet for full information.
