PRODUCT OVERVIEW
Fabricated on a Single Inline Package (SIP) module,
the LSS-T/10-W12 series is a miniature non-iso-
lated Point-of-Load (POL) switching DC/DC power
converter for embedded applications. The converter
offers both tight regulation and high efficiency
directly at the power usage site. Typically, no extra
outside components are required. The module
mounts vertically, occupying a tiny board footprint.
The upright mounting improves cooling airflow.
Suggested applications include powering CPU’s,
distributed bus architectures (DBA) with a master
bus power supply, programmable logic and mixed
voltage systems.
Based on synchronous buck converter topology,
the extraordinary efficiency means very low heat
and little electrical noise. The ultra wide input
range is 4.5 to 13.8 Volts. Additional features
include quick transient response to step loads and
stable no-load operation. A key feature is select-
able output voltage either by precision resistor,
trim pot or user’s voltage input. The output range is
adjustable from 0.6 to 6 Vdc.
A wealth of protection features prevents damage
to both the converter and outside circuits. Inputs
are protected from undervoltage and outputs offer
short circuit protection, overcurrent and excess
temperature shut down. The unit is designed to
meet all EMI/RFI certifications as well as HALT
reliability. RoHS6 hazardous material compliance
is specified as standard. All units are precision
assembled in a highly automated computer-
controlled surface mount facility with ISO-traceable
manufacturing quality standards. Additional system
functions include a remote On/Off control.
