NOTES

(1) All parameters measured at Tc=25°C, nominal input voltage and full rated load unless otherwise noted.

(2) Measurement bandwidth is 20 MHz. Input Reflected Ripple and output noise are measured with an exter-

nal 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 capaci-

tance 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 350KHz is required. If a capacitive input source

is farther than 2” from the converter, it is recommended to

use a 10␮F, 25V 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.
