| 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. FEATURES * Non-Isolated * High Efficiency Topology * Excellent Transient Response * Sense and Power OK (SIE Model Only) 4.5 - 5.5 VDC TECHNICAL SPECIFICATIONS Input Voltage Range 5 VDC Nominal * Surface-Mount Construction * Voltage Trim * Vertical or Horizontal Mounting * Water Washable Efficiency vs. Load Output Setpoint Accuracy Line Regulation Vin Min. - Vin Max., Iout Rated Load Regulation Iout Min.- Iout Max., Vin Nom.
