DESCRIPTION
The SuperVerter series modules are high-density DC-DC converters designed for use in
telecom and other centralized, modular, and distributed power applications. The SV28-3.3
series is a family of 28V input, 3.3V output, half brick modules compatible with the industry
standard footprint. These modules may be used as form, fit, and function replacements for
industry standard, 3.3V half brick modules. These SuperVerter modules use metal
baseplates, planar transformers, and surface mount construction to produce up to 132W of
low noise, 3.3V output power.
