(2) The functional temperature range is intended to give an additional data point for use in evaluating this power supply. At the low functional temperature the power supply will function with no side effects, however, sustained operation at the high functional temperature will reduce expected operational life. The data sheet specifications are not guaranteed beyond the case operating range. (3) The case thermal impedance is specified as the case temperature rise over ambient per package watt dissipated.

To meet the reflected ripple requirements of the converter, an input impedance of less than 0.09 Ohms from at 220KHz is required. External output capacitance is not required for operation, however it is recommended that 1mF to 10mF of tantalum and 0.001 to 0.1mF ceramic capacitance be selected for reduced system noise. Additional output capacitance may be added for increased filtering, but should not exceed 400mF. All parameters measured at Tc=25C, nominal input voltage and full rated load unless otherwise noted. Refer to the DC/DC Technical Reference Section for the definition of terms, measurement circuits and other information. Noise is measured per DC/DC Technical Reference Section. Measurement bandwidth is 0-20 MHz for peak-peak measurements, 10 kHz to 1 MHz for RMS measurements. Output noise is measured with a 1F tantalum located 1" away from the converter to simulate PCB standard decoupling. Input reflected ripple is measured into a 1 H source impedance. Optimum performance is obtained when this power supply is operated within the minimum to maximum load specifications. Output regulation is specified by simultaneously changing from minimum to maximum load and noting the change in each output. Cross regulation is defined as the change in one output when the other output is changed from full load to 25% of full load. The converter can be run at no load on either or both outputs with no damage. Short term stability is specified after a 30 minute warmup at full load, constant line and recording the drift over a 24 hour period. 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/ drain 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. The input capacitors are kept fully charged in the OFF mode. For proper operation, do not drive this input from a logic gate directly. The ON/OFF pin should never be pulled more than 0.3 volts below -INPUT or have a voltage greater than +8 volts applied. DGP20 SERIES APPLICATION NOTES: External Capacitance Requirements No external capacitance is required for operation of the DGP20 Series. However, for maximum performance, it is recommended that the DGP20 Series use a capacitor of sufficient ripple current capacity 50 (800) 678-9445 * FAX: (805) 388-0476 DGP20 SERIES - TRIPLE OUTPUT DGP20 SERIES BLOCK DIAGRAM OUTPUT POWER DERATING 20 SHIELDED ISOLATION TRANSFORMER + - INPUT 2 ON/OFF 3 LOW NOISE FILTER +5V OUTPUT 4 +12/15V OUTPUT 6 CMN 7 -12/15V OUTPUT 15 + 1 + INPUT 5 POWER OUTPUT + CURRENT MODE PWM + 10 5 - 0 50 SHIELDED COPPER CASE 60 70 80 90 AMBIENT TEMPERATURE 100 Typical Performance: (Tc=25C, Vin=Nom VDC, Rated Load) 12 VOLT INPUT CURRENT Vs.
