DESCRIPTION

The DGP20 Series is a high performance 20 watt triple output DC/DC converter designed for battery and telecom applications. Power densities of up to 11 watts per cubic inch provides system flexibility. The extended 2:1 input voltage range allows operation over a wide variety of sources from 9 to 72 volts.

FEATURES

  • Triple Outputs
  • Five Sided Shielded Case
  • Remote ON/OFF
  • Efficiencies to 84%
  • -40°C to +85°C Operation
  • 700Volt Isolation
  • Extended Range Input (2:1) DGP20 SERIES TRIPLE OUTPUT Mechanical tolerances unless otherwise noted: X.XX dimensions: ±0.020 inches X.XXX dimensions: ±0.005 inches NOTES (1) All parameters measured at Tc = 25°C, 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) 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. (4) Case is tied to-Input, Pin 2. BOTTOM VIEW SIDE VIEW 0.000 0.000 0.25 0.000 2.02 (51.31) (6.35) 0.040 (1.02) DIA

DGP20 SERIES – TRIPLE OUTPUT NOTES (1) All parameters measured at Tc=25 ° C, 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) Noise is measured per 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 1µF tantalum located 1" away from the converter to simulate PCB standard decoupling. Input reflected ripple is measured into a 1 µH source impedance. (3) Optimum performance is obtained when this power supply is operated within the minimum to maximum load specifications. (4) Output regulation is specified by simultaneously changing from minimum to maximum load and noting the change in each output. (5) 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. (6) Short term stability is specified after a 30 minute warmup at full load, constant line and recording the drift over a 24 hour period. 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 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 0.09 Ohms from at 220KHz is required. External output capacitance is not required for operation, however it is recommended that 1 /H9262F to 10/H9262F of tantalum and 0.001 to 0.1 /H9262F ceramic capacitance be selected for reduced system noise. Additional output capacitance may be added for increased filtering, but should not exceed 400 /H9262F. 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.
