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.
