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 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.
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.
