DSP1N5D5

DSP1 SERIES DUAL OUTPUT DESCRIPTION The DSP1 Series is specifically designed to convert a nominal 5 volt input into two isolated output voltages. The dual semiregulated 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. FEATURES 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 FRONT VIEW 0.40 (10.16) RT +OUT -OUT CMN 0.02 (0.51) 0.000 1 2 3 4 5 SIDE +IN -IN VIEW 0.27 (6.86) 0.77 0.000 0.09 0.200 (5.08) 0.100 (2.54) 0.400 (10.16) 0.500 (12.70) PINS: 0.02 (0.51) x 0.01 (0.25) LENGTH (TYPICAL): 0.15 (3.81) Mechanical tolerances unless otherwise noted: X.XX dimensions: ±0.020 inches X.XXX dimensions: ±0.010 inches DSP1 SERIES APPLICATION NOTES: External Capacitance Requirements Output filtering is required for operation. A minimum of 10␮F is specified for optimal performance. Output capacitance may be increased for additional filtering, and should not exceed 400␮F. 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 10␮F, 25V solid tantalum capacitor....
