DSP1 Single-Output DC-DC Series Data Sheet 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 350 kHz fixed-frequency switching converters. Features * RoHS lead solder exemption compliant * Up to 1 watt unregulated output power * Single in line package * Four-terminal operation * Efficiencies to 75% * 350 kHz fixed-frequency operation * 700 V isolation * -40 C to +85 C operation FRONT VIEW 0.40 (10.16) Selection Chart All Models Case Operating Range, Tc (3) Storage Range Thermal Impedance (2) General MTBF (Calculated) Unit Weight Case Material +OUT 3 4 0.77 (19.56) Units MIN 700 VDC TYP 25 pF MIN MAX MIN MAX TY P -40 +85 -55 105 58 C TYP TYP 2 (15.24) General Specifications (1) Isolation Isolation Voltage Input to Output 10A Input to Output Capacitance Environmental 1 0.000 0.600 0.75 1.0 1. 0 1. 0 1. 0 1. 0 -OUT 150 140 80 70 65 60 0.400 DSP1N5S17 5 7 12 14 15 17 (0.51) (10.16) DSP1N5S15 5.5 5.5 5.5 5.5 5.5 5.5 0.02 -IN DSP1N5S14 4.5 4.5 4.5 4 .5 4 .5 4 .5 Power W 0.200 (5.08) DSP1N5S7 DSP1N5S12 Max Output mA +IN DSP1N5S5 Mi n Output VDC 0.100 (2.54) Model 0.000 Input Range VDC Mechanical tolerances unless otherwise noted: X.XX dimensions: 0.020 inches X.XXX dimensions: 0.010 inches * This dimension to decrease to 0.240.01" (6.090.25) in 1998 ** This dimension to decrease to 0.0350.015" (0.890.38) in 1998 C C/Watt 700,000 HRS 0.1 / 2.8 oz / gm Non Conductive Plastic Pin 1 2 3 4 Function +INPUT -INPUT -OUT +OUT NOTES (1) (2) (3) All parameters measured at Tc = 25 C, nominal input voltage and full rated load unless otherwise noted.

(2) Noise measurement bandwidth is 20 MHz. Input Reflected Ripple and output noise are measured with an external 10F/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. 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, not to exceed 400 F. To meet the reflected ripple requirements of the converter, an input impedance of less than 0.5 Ohms from DC to 350 kHz is required. If a capacitive input source is farther than 2" from the converter, it is recommended to use a 10 F, 25 V 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.
