DVCH2800S DC-DC Converter

The DVCH Series of DC-DC converters delivers just 1.5 watts in the most efficient, small-size package available today for use in critical-reliability applications. The extra-wide input voltage range, very low output noise, and high reliability ensures the DVCH is the perfect low power choice for your next space or avionics program.

Features:

  • Single outputs of 3.3V, 5V, 5.2V, 12V, and 15V
  • Extra-wide 12V to 50V input range with 80V transient per MIL-STD-704
  • Up to 1.5W output power
  • Full operation over -55 °C to +125 °C military temperature range
  • Fault tolerant design with patented technology – no optoisolators
  • Very low input/output noise
  • High reliability magnetic feedback circuit
  • Tiny size – 0.975″x 0.8″ x .27″ and light weight (11g)
  • Host of circuit protection features
