DESCRIPTION
The MIL-COTS V•I ChipTM bus converter is a high efficiency
(>95%) Sine Amplitude ConverterTM (SACTM) operating from a
240 to 330 Vdc primary bus to deliver an isolated 30 – 41.25 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.
VIN = 240 – 330 V
VOUT = 30 – 41.25 V (NO LOAD)
POUT = 235 W(NOM)
K = 1/8
TYPICAL APPLICATIONS
• High Voltage 270 V Aircraft Distributed Power
• 28 Vdc MIL-COTS PRMtm Interface (MP028F036M21AL)
• High Density Power Supplies
• Communications Systems
