Description
The MIL-COTS VI Chip^® bus converter is a high efficiency (>96.0%)
Sine Amplitude Converter™ (SAC™) operating from a 230 to 330V
primary bus to deliver an isolated 38.3 – 55.0V secondary voltage.
The MBCM270F450M270A00 is provided in a VI Chip package
compatible with standard pick-and-place and surface mount
assembly processes.
