External Capacitance Requirements:
Output filtering is required for operation. A minimum of 10F is specified for optimal performance. Output capacitance may be increased for additional filtering, not to exceed 400F. To meet the reflected ripple requirements of the converter, an input impedance of less than 0.5 Ohms from DC to 350KHz is required. If a capacitive input source is farther than 2" from the converter, it is recommended touse a 10F, 25V solid tantalum capacitor.
Regulation
This converter uses a semi-regulated design. The output will vary as the load is changed, with output decreasing with increasing load. See Output Voltage vs. Output Load curves.
Additionally, output voltage will change in proportion to a change in input voltage. The typical output voltage will change 1.2% for each 1% change in input voltage.
Negative Outputs
A negative output voltage may be obtained by connecting the +OUT to circuit ground and connecting -OUT as thenegative output.
The DSP1 Series is specifically designed to convert a nominal 5 volt input into an isolated output voltage. The semi-regulated output voltages of DSP1 Series vwere designed to allow analog circuits and three terminal regulators to operate within their most efficient input voltage range. This DSP1 Series achieves high power densities through the use of 350KHz fixed frequency witchingconverters.
