POWER-ONE 
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

NOTES
DSP1 SERIES APPLICATION NOTES:
(1) All parameters measured at Tc=25°C, nominal input voltage and full rated load unless otherwise noted.
(2) Measurement bandwidth is 20 MHz. Input Reflected Ripple and output noise are measured with an exter-
nal 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.
External Capacitance Requirements
Output filtering is required for operation. A minimum of
10ꢀF is specified for optimal performance. Output capaci-
tance may be increased for additional filtering, not to
(6) Use input fuse for protection. See Applying the input.
exceed 400ꢀF. 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 10ꢀF, 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 the
negative output.
