DSP1 Single-Output DC-DC Series Data Sheet
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

DSP1 Series Application Notes:

noted.

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 to use a 10F, 25V solid
tantalum capacitor.
measured with an external 10µF/25V tantalum capacitor connected across the input and output
pins.
(3) Output Voltage Accuracy measured at 75% of maximum Rated Load.
(4) Load Regulations measured relative to 75% of maximum Rated Load Current.
(5) Line Regulation is for a 1.0% change in input Voltage.
(6) Use input fuse for protection. See Applying the input.
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 the negative
output.
