Description

The DVHF Series of converters packs up to 30% more power in an industry standard size. Designed for smooth start-up, the DVHF prevents voltage overshoots.

Features

  • Dual outputs of ±5V, ±12V, and ±15V
  • Extra-wide 15V to 50V input range with 80V transient
  • Up to 20W output power
  • High power density: 37W/in3
  • Full performance over -55°C to +125°C military temperature range
  • Fault tolerant design with patented technology – no optocouplers
  • Host of circuit protection features
  • Fixed switching frequency
  • Extremely low profile (.355 inches) and light weight (24/28g max) fully hermetic packaging
  • Ensure excellent thermal performance and unit isolation by using with the thermal pad TP-002.
