Description

A VTM™ current multiplier puts isolated current multiplication and voltage division directly at the point of load (POL), and an upstream PRM™ regulator controls the factorized bus voltage supplied to the VTM to provide line and load regulation. Together, the PRM and VTM chip set provides the full functionality of a DC-DC converter, but with breakthrough performance and flexibility in a rugged, miniature package.

The MIL-COTS PRM operates from a wide input range of 16 – 50 Vdc, meeting many of the ground vehicle and airborne requirements of MIL-STD-1275 and MIL-STD-704. Rated for 120 W, the 28 V PRM produces a nominal factorized bus voltage of 36 Vdc, controllable over the range of 26 – 50 Vdc. The downstream isolated VTM is available with twelve voltage division ratios from 1:1 to 1:32 and provides the user with flexibility to supply up to 100 A or 120 W at any output voltage from 1 to 50 Vdc in a surface-mount package occupying only 1 square inch.

Input Voltage:
  • PRM: 16 – 50 V
  • VTM: 26 – 50 V
Output Voltage:
  • PRM: 26 – 50 V
  • VTM: 0.8 – 50 V
Output Power (per module):
  • VTM: Up to 100 A
  • PRM: 120 W
Operation:
  • –55°C to 125°C operation
Dimensions per module:
  • 1.28″ x 0.87″ x 0.265″
    (32.5 x 22.0 x 6.73 mm)
