Delivering Next Generation Technology
Series
FGSR12SR6006*A
Data Sheet
3-14.4Vdc Input, 6A, 0.6-5.5Vdc Output
The
Tomodachi
Series of non-isolated dc-dc
converters deliver exceptional electrical and thermal
performance in DOSA based footprints for
Point-of-Load converters. Operating from a
3.0Vdc-14.4Vdc input, these are the converters of
choice for Intermediate Bus Architecture (IBA) and
Distributed Power Architecture applications that
require high efficiency, tight regulation, and high
reliability in elevated temperature environments with
low airflow. The Tunable Loop™ feature allows the
user to optimize the dynamic response of the
converter to match the load with reduced amount of
output capacitance leading to savings on cost and
PWB area.
The
FGSR12SR6006*A
converter of the
Tomodachi
Series delivers 6A of output current at a tightly
regulated programmable output voltage of 0.6Vdc to
5.5Vdc. The thermal performance of the
FGSR12SR6006*A
is best-in-class: No derating is
needed up to 85℃, under natural convection.
