DSP1 SERIES
SINGLE OUTPUT
DESCRIPTION
FEATURES
The DSP1 Series is specifically designed to convert a nominal 5
volt input into an isolated output voltage. The semi-regulated
output voltages were designed to allow analog circuits and three
terminal regulators to operate within their most efficient input
voltage range. This series achieves high power densities through
the use of 350KHz fixed frequency switching converters.
• Up to 1 Watt Unregulated Output Power
• Single In Line Package
• Four Terminal Operation
• Efficiencies to 75%
• 350KHz Fixed Frequency Operation
• 700V Isolation
• -40°C to +85°C Operation
