Refer to the DC/DC 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.

(1) All parameters measured at Tc=25°C, 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.
(2) 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
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.
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 1F to
10F of tantalum and 0.001 to 0.1F ceramic capacitance be
selected for reduced system noise. Additional output capacitance
may be added for increased filtering, but should not exceed 400F.
(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.
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
