SIP/SIE 500 SERIES - NON-ISOLATED, 20 WATT
DESCRIPTION
SIP/SIE non-isolated step-down DC/DC converters
deliver high efficiency and excellent transient response in
an industry-standard SIP package. The SIP/SIE Series has
output voltages ranging from 1.2 to 3.3V and up to 6 amps
of output current. The SIE model has power OK and
remote sense pins for added flexibility and improved point-
of-load regulation. The SIP/SIE Series is available for
vertical or horizontal mounting. The SIP/SIE Series uses
100% surface-mount construction for maximum reliability
and features over seven million hours MTBF.
