DESCRIPTION
The MIL-COTS Vâ¢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 â 41.25 V
nominal, unregulated secondary.
The VMB0004MFJ and VMB0004MFT are provided in a
Vâ¢I Chip package compatible with standard pick-and-place and
surface mount assembly processes.
VIN = 240 â 330 V
VOUT = 30 â 41.25 V (NO LOAD)
POUT = 235 W(NOM)
