SIE501.2LT

SIP/SIE500 DC-DC Series Data Sheet Non-Isolated, 20 Watts Features • • • • • • • • Non-Isolated High Efficiency Topology Excellent Transient Response Sense and Power OK (SIE Model Only) Surface-Mount Construction Voltage Trim Vertical or Horizontal Mounting Water Washable 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% surfacemount construction for maximum reliability and features over seven million hours MTBF.
