Description
The DSP1 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.
densities through the use of 350 kHz fixed-frequency
switching converters.
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 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.
