SGS SERIES - NON-ISOLATED, 100 WATT
DESCRIPTION
SGS non-isolated buck converters provide up to 100
Watts of power at up to 30 Amps of output current in an
industry standard half-brick package. The SGS series
uses a high efficiency, non-isolated topology to provide
excellent efficiency and transient response. The SGS has
open-frame packaging and high temperature planar
magnetics to provide exceptional thermal performance.
The SGS uses 100% surface-mount construction and has
a predicted reliability of over one million hours MTBF.
