Power Solutions is set to change the shape of 1 Watt isolated surface-mount
DC-DC converters. The introduction of its high performance MTU1 series marks a
step-change in the miniaturization of power modules, setting new standards for
footprint, load regulation, and efficiency.
The
latest design techniques and materials have been used to reduce the module’s
footprint while improving electrical performance characteristics. The MTU1
series’ dimensions are 8.2 × 8.4 × 8.5 mm, representing a footprint reduction
of 50% compared to the previous generation. Power density is 1.71 W/cm3 and the
series features wide temperature performance at full 1 Watt load, between -40
and 85ºC. The series’ load regulation has been enhanced to only 7.5%, a change
of 40%.
The
DC-DC converter also features 56% less power dissipation and lower running
temperatures than its predecessor, improving overall efficiency by more than a
fifth to 89%. The increase in efficiency and benefit of reduction in power
dissipation enables the series’ open frame design. The greatly improved
efficiency of the MTU1 series also contributes to its lower energy consumption
and greater reliability.
