Datasheet Bel DSP1 D — Даташит

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. п‚ RoHS lead solder exemption compliant п‚ Up to 1 Watt unregulated output power п‚ Single-In-Line package п‚ Four-terminal operation п‚ Efficiencies to 70% п‚ Output Voltages: 5V, 7V, 12V, 14V, 15V, 17V п‚ 700 V isolation п‚ -40 В°C to +85 В°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.

Derate output power linearly to 0.6 watts from 70 В°C to 85 В°C. [email protected] DSP1D Series 3 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 ОјF. 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 ОјF, 25 V solid tantalum capacitor. …
