(5.5v) SIP/SIE 500 NON-ISOLATED SERIES 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.

  • Non-Isolated
  • High Efficiency Topology
  • Excellent Transient Response
  • Sense and Power OK (SIE Model Only)
