DSP1 SERIES
DUAL OUTPUT
DESCRIPTION
FEATURES
The DSP1 Series is specifically designed to convert a nominal 5
volt input into two isolated output voltages. The dual semi-
regulated output voltages are 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 70%
• Output Voltages: 5V, 7V, 12V, 14V, 15V, 17V
• 700V Isolation
• -40°C to +85°C Operation

DSP1 SERIES APPLICATION NOTES:
External Capacitance Requirements
Output filtering is required for operation. A minimum of 10ꢀF is
specified for optimal performance. Output capacitance may be
increased for additional filtering, and should not 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.
NOTES
(1) All parameters measured at Tc=25 °C case temperature, nominal input voltage and full rated load
unless otherwise noted.
(2) Derate output power linearly to 0.6 watts from 70°C to 85°C.
Regulation
This converter uses a semi-regulated design. The output will vary as
the load is changed, with output decreasing with increasing load.
Additionally, output voltage will change in proportion to a change
in input voltage. The typical output voltage will change 1% for each
1% change in input voltage.
