Power-one DGP12U5D5, DGP12U5D15, DGP12U5D12 Datasheet

DESCRIPTION

The dual output DGP12 Series provides symmetrical +/– outputs from 5 volts to 15 volts in packages that provide power densities up to 7 watts per cubic inch (0.43 watts per cm

). Designed to operate on ultra-wide input voltages from 3.5 to 16 volts, and with remote ON/OFF capability, the DGP12 supplies power from battery or system sources . The fully isolated, shielded case allows precise operation in sensitive environments.

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) See the DGP12 Series Application Notes for more information on applying the ON/OFF pin. (3) The Case is tied to the -Input pin. (4) 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. (5) The case thermal impedance is specified as the case temperature rise over ambient per package watt

dissipated. (6) Output power is reduced at 3.5V input. See DGP12 Series Application Notes for specific

Derating guidelines

NUCLEAR AND MEDICAL APPLICATIONS Power-One products are not authorized for use as critical components in life support systems, equipment used in hazardous environments, or nuclear control systems without the express written consent of the President of Power-One, Inc.

TECHNICAL REVISIONS The appearance of products, including safety agency certifications pictured on labels, may change depending on the date manufactured. Specifications are subject to change without notice.

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 1

F to 10F of tantalum and 0.001 to 0.1F ceramic capacitance be selected for reduced system noise. Additional output capacitance may be added for increased filtering, but should not exceed 400F.

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.
