Description

A true military and avionics grade thick-film hybrid DC-DC power converter, the DVSB Series eliminates the need for custom converters or multiple converters to satisfy multiple output voltage needs in a mil/aero power system. With outputs 3.3V and 5V, the DVSB Series can power systems from a single module, saving board space, weight, and development cost while enhancing the system reliability.

Features

  • Dual low voltage outputs of ±3.3V and ±5V
  • Wide input voltage range: 15 to 50 Volts with 80V transient per MIL-STD-704
  • Up to 12.5 watts output power
  • Full performance over -55°C to +125° C. military temperature range
  • Minimal cross regulation resulting from VPT’s dual control loop design topology
  • Fault tolerant magnetic feedback circuit
  • Extreme reliability: no use of optoisolators
  • Very low output noise: 40mV typical
  • Host of circuit protection features
  • Extremely low profile (.355 inches) and light weight (24/28g) hermetic package
  • Fixed switching frequency
  • Ensure excellent thermal performance and unit isolation by using with the thermal pad TP-007

Compliances and Certifications

  • Available qualified to MIL-PRF-38534 Class H and Class K, DLA SMD #5962-08207
  • MIL-PRF-38534 Class H and Class K certified manufacturing facility
  • MIL-STD-704A input voltage requirements
  • DO-160
  • ISO-9001
  • MIL-STD-883 military and space environmental screening available
  • MIL-STD-461 C-F when used with a VPT DVMH28 EMI filter
