The
D
series DC-DC converters feature high power density, high efficiency and
excellent line & load regulation. Using innovative design technique, state-of-the
art Current Mode PWM control, and Surface Mount packaging & manufacturing
technology, the D series provides up to 15 watts of well regulated power in a
encapsulated 1.0” x 2.0” x 0.40” metal case with six-sided EMI/RFI shielding.
Automatic feed forward compensation, pulse-by-pulse current limiting, and output
short circuit protection are standard for all models.
These converters are designed for wide input range telecommunications,
industrial and instrument applications. The wide input range (2:1 & 4:1) is ideal for
battery or unregulated input applications.
FEATURES
General:
• Small footprint : 1.0” x 2.0”
• Current-Mode Control
• Input/Output Isolation
• Input Voltage from 9 to 75Vdc
• 2:1 & 4:1 Input Voltage Range
• High conversion efficiency: 80%
• Line & load regulation to ±1.0%
• Fixed operating frequency
• Six-Sided Shielding
Isolation:
• Isolation Voltage >500V
APPLICATIONS
• PoE (Power over Ethernet)
• Distributed Power Systems
• Workstations
• Computer Equipment
• Communications Equipment
No external components are needed for normal operation. Low ESR capacitors
are used to minimize the conductive noise. This package is ideal for all I/O board
system and distributed DC power configurations.
