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.
