1.0 DESCRIPTION
The VXR series of isolated DC-DC converters is the latest and
most advanced offering in VPT’s extensive line of high
reliability COTS products. Building on a proven design heritage,
the VXR series features high efficiency, an ultra-wide input
voltage range, and next-generation packaging. Providing a
wide 9 V to 60 V input, along with VPT’s standard full feature
set and industry-leading performance, the VXR family is
optimized for a broad range of applications from military
ground vehicles to commercial and military aircraft.
The VXR15 utilizes a low noise, fixed frequency, wide input
voltage range topology with extended high and low input
transient capability to simplify overall power system design
and compliance. Precision controlled synchronous rectification
achieves high efficiency over a wide input range, reducing
power dissipation and minimizing external heatsink
requirements. A proprietary control loop design provides fast
transient response without the use of optoisolators.
The VXR Series patent-pending epoxy-encapsulated
V-SHIELD® packaging is highly resistant to chemical, solvent
and salt environments and is fully compatible with high
volume manufacturing processes including wave solder,
cleaning solvents, high pressure sprays and aqueous wash
processes. A unique integral six-sided metalized shield
improves system EMI compatibility. Dual sided conduction
cooling coupled with reduced power dissipation simplifies
system thermal design.
The VXR series is intended for harsh environments including
severe vibration, shock and temperature cycling. Testing is to
JESD22, MIL-STD-810, and MIL-STD-883.
