Martek Power has extended its CB range of 28V input DC-DC converters with a 75W triple output device.

Available now with 3.3V or 5V main and +/-12V or +/-15V auxiliary outputs. The design has a power density of 27W/cubic inch into dimensions of 2.0x2.75x0.5 inches and offers efficiency greater than 85%.

With an operating temperature range of -55 to +100 deg C - without derating - and full encapsulation, they are suitable for use in military or other extreme environments.

Standard features include 16V to 40V input range, 500kHz fixed frequency switching, synchronisation, remote switch-on and full protection from over-voltage, over-current and over-temperature conditions.

All are available in I (unscreened and M (screened) grades.
