NOTES
(1) 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 10μF/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.

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, 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.
