Overview
Powering Communications and Technology SIP/SIE 500 NON-ISOLATED SERIES 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 use 100% surface-mount construction for maximum reliability and feature over seven million hours MTBF.
