The VXR Series employs a fixed frequency, low noise, wide input voltage range topology which features extended high and low input transient capability to simplify overall power system design and compliance.
Precision controlled synchronous rectification achieves optimal efficiency over a wide input range, minimising external heatsink requirements and reducing power dissipation. A proprietary control loop design also provides fast transient response without optoisolators.
VPT’s patented epoxy encapsulated packaging is extremely resistant to solvent, chemical and salt environments and is fully compatible with high volume manufacturing processes, including cleaning solvents, high pressure sprays, wave solder, and aqueous wash.
A unique and integral metalised shield boosts system EMI compatibility. Dual-sided cooling coupled with reduced power dissipation simplifies your system’s thermal design.
VPT’s high-reliability COTS DC-DC converters have been developed to meet a wide range of demanding military requirements, including unmanned systems.
COTS products from VPT are available immediately from stock.
