Single Output


Features, Applications

DESCRIPTION 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.

NUCLEAR AND MEDICAL APPLICATIONS Power-One products are not authorized for use as critical components in life support systems, equipment used in hazardous environments, or nuclear control systems without the express written consent of the President of Power-One, Inc. TECHNICAL REVISIONS The appearance of products, including safety agency certifications pictured on labels, may change depending on the date manufactured. Specifications are subject to change without notice.

All parameters measured at Tc=25�C, nominal input voltage and full rated load unless otherwise noted. Measurement bandwidth is 20 MHz. Input Reflected Ripple and output noise are measured with an external 10�F/25V tantalum capacitor connected across the input and output pins. Output Voltage Accuracy measured 75% of maximum Rated Load. Load Regulations measured relative 75% of maximum Rated Load Current. Line Regulation is for a 1.0% change in input Voltage. Use input fuse for protection. See Applying the input.

DSP1 SERIES APPLICATION NOTES: External Capacitance Requirements Output filtering is required for operation. A minimum 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 350KHz is required. If a capacitive input source is farther than 2" from the converter, it is recommended to use 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 the negative output.
