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. 1.1 FEATURES Wide input voltage range: 9 V to 60 V 6 V to 80 V transient for 1 second, 100 V for 200 milliseconds High Efficiency up to 87% Rugged Epoxy Encapsulated V-SHIELD® Package Fully compatible with aqueous cleaning processes Integral Six-sided Metalized EMI shield Dual-Sided Thermal Conduction 2000 V Isolation Fixed frequency Low noise Output Voltage Trim (+10% / -20%) Output Current Limit Protection Short Circuit Protection 1.2 COMPLIANCE MIL-STD-1275 A-E RTCA / DO-160-Section 16 MIL-STD-704 A-F MIL-STD-461 C-F when used with an appropriate VXR EMI filter RTCA / DO-160-section 18 and 21 when used with an appropriate VXR EMI filter 1.3 PACKAGING Low-profile:1.410” x 1.170” x 0.350” Optional package with mountingholes available Max weight:Standard 30 g / Optional 40 g 1.4 SIMILAR PRODUCTS AND ACCESSORIES DVHF 20 W single outputMilitary Qualified DC-DCConverter VPT15 15 W single output metal package COTS DC-DC Converter EMI filters, Thermal Pads, Front-End Modules and Accessories |
