DGP12 SERIES – DUAL 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) Reduced output power available below 9 volts input. See DGP12 Series Applications Notes for more
information.
(3) No minimum load required for operation.
(4) Load regulation is defined for loading/unloading both outputs simultaneously. Load range is 25 to
100%.
(5) Cross regulation is defined for loading/unloading one output while the other output is kept at full load.
Load range is 25 to 100%.
(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.
(7) 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/35V Tantalum capacitor located 1" away from the converter to simulate PCB standard
decoupling.
DGP12 SERIES APPLICATION NOTES:
External Capacitance Requirements
No external capacitance is required for operation of the DGP12
Series. To meet the reflected ripple requirements of the converter,
an input impedance of less than 0.05 Ohms from DC to 100KHz
is required. If a capacitive input source is farther than 1” from the
converter, an additional capacitor may be required at the input
pins for proper operation. 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.
Output Power
The available output power of the DGP12 Series is reduced when
operating below 9 volts. See Input Voltage Derating curve. Below
4.6 volts the output power is derated to 50% at 3.5 volts.
