DGP30 SERIES
SINGLE OUTPUT
DESCRIPTION The single output DGP30 Series is designed to accept an extended 2:1 input voltage range for use in industrial and telecom applications. The output of the converter is electrically isolated, thereby allowing the output to be configured as a positive or negative output voltage. For additional system utility output Trim and Remote ON/OFF are featured. Overcurrent protection, overtemperature protection, and output overvoltage transient protection allow safe, reliable operation. FEATURES * Remote ON/OFF and TRIM * Low OFF Current * Overcurrent and Overtemperature Protection * Efficiencies to 86% * Transient Output Overvoltage Protection * 1544V Isolation * Five-Side Shielded Case * Extended Range Input (2:1)

NOTES (1) All parameters measured at Tc = 25C, nominal input voltage and full rated load unless otherwise noted. Refer to the Technical Reference Section for the definition of terms, measurement circuits and other information. (2) ON/OFF pin is referenced to pin 2, -Input. See DGP30 Series Application Notes for the specific requirements of this feature. (3) The Case is electrically connected to Pin 1, +Input. (4) Full output trim range may not be available at minimum input voltage and full load. Full trim is guaranteed from minimum input voltage, plus 5%, and full load. (5) The case thermal impedance is specified as the case temperature rise over ambient per package watt dissipated.

NOTES
(1) All parameters measured at Tc=25 C case temperature, nominal input voltage and full rated load unless otherwise noted. Refer to the Technical Reference Section for definition of terms, measurement circuits and other information. Minimum load required for rated regulation only. Module will not be damaged if run at less than minimum load. Short term stability is specified after a 30 minute warm-up at full load, and with constant line, load and ambient conditions. The input ripple rejection is specified for DC to 120Hz ripple with a modulation amplitude of 1% Vin. Noise is measured per Technical Reference Section. Output noise is measured with a 1F tantalum capacitor connected 1" from the output pins.

DGP30 SERIES - SINGLE OUTPUT
DGP30 SERIES APPLICATION NOTES: External Capacitance Requirements No external capacitance is required for operation of the DGP30 Series. However, it is recommended that the DGP30 Series use a capacitor of sufficient ripple current capacity connected across the input pins if a capacitive input source is farther than 1" from the converter. To meet the reflected ripple requirements of the converter, an input impedance of less than 0.05 Ohms from DC to 200KHz is required. External output capacitance is not required for operation, however it is recommended that 1 F to 10 F of tantalum and 0.001 to 0.1 F ceramic capacitance be selected for reduced system noise. Additional output capacitance may be added for increased filtering, but should not exceed 400 F. Negative Outputs A negative output voltage may be obtained by connecting the +OUT to circuit ground and connecting -OUT as the negative output. Remote ON/OFF Operation The remote ON/OFF pin may be left floating if this function is not used. It is recommended to drive this pin with an open collector arrangement or a relay contact. When the ON/OFF pin is pulled low with respect to the -INPUT, the converter is placed in a low power drain state. Since the ON/OFF pin is driven by a 9 volt internal source via a 100K resistor, the pin should not be driven by TTL logic. Attempts to drive this circuit with logic circuits may result in damage to user circuitry.
Output TRIM The TRIM pin may be used to adjust the output 5% from the nominal setting. This function allows adjustment for voltage drops in the system wiring, as well 5.2 volt outputs for ECL applications. Figure 1 shows the proper connections to use this function. A trimpot value of 10K should be used for the 5 volt output. A trimpot value of 20K should be used for 12 and 15 volt outputs. If the TRIM function is not required the pin may be left floating.
