DESCRIPTION
The MIL-COTS V•I Chip Bus Converter Module is a high
efficiency (>95%) Sine Amplitude Converter (SAC) operating
from a 240 to 330 Vdc primary bus to deliver an isolated
30 – 41.2 V nominal, unregulated secondary.
The VMB0004MFJ and VMB0004MFT are provided in a
V•I Chip package compatible with standard pick-and-place and
surface mount assembly processes.
V_IN = 240 – 330 V
V_OUT = 30.0 – 41.25 V (NO LOAD)
P_OUT = 235 W(NOM)
K = 1/8
TYPICAL APPLICATIONS
• High Voltage 270 V Aircraft Distributed Power
• 28 Vdc MIL-COTS PRM Interface (MP028F036M12AL)
• High Density Power Supplies
• Communication Systems
