DSP1N5D5

The DSP1D Series is specifically designed to convert a nominal 5 volt input into two isolated output voltages. The dual 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.  RoHS lead solder exemption compliant  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  700 V isolation  -40 °C to +85 °C operation DSP1D Series 2 INPUT RANGE [VDC] OUTPUT MODEL MIN MAX [VDC] [mA] POWER [W] xxxx Model numbers highlighted in yellow are not recommended for new designs.

A minimum of 10 F is specified for optimal performance. Output capacitance may be increased for additional filtering, and should not exceed 400 μF. 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 μF, 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. 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. Figure 1.
