5 W surface mountable DC-DC converter

9 May 2001 Power Electronics / Power Management

Interpoint offers the MSM series of DC-DC converters delivering up to 5 W from a 28 V input in a surface mountable package. Mature design technology incorporated in the series maintains high-reliability, providing full power operation over the full military temperature range of -55° to +125°C.

The MSM series uses commercially available discrete components, PCB construction and surface mount technology, keeping costs at a minimum while providing a maximum weight of 20 g in a compact package (51,1 x 51,18 x 7,9 mm). The package can be surface mounted or hand-soldered. Output voltages of 3,3, 5, 5,2, 12, 15, ±12, or ±15 operate from an input range of 16 to 40 V d.c.

The MSM series features a proprietary magnetic isolator, designed with feed-forward and load correction, providing nearly instantaneous output control for good regulation. An inhibit function for remote shut-down and restart provides added functionality. Protection features include undervoltage lockout and soft-start to prevent start-up problems; short circuit and overload protection to limit current draw and prevent damage to the converter; and transient protection of 80 V for up to 120 ms.
