DESCRIPTION
With up to 120 watts of output power, the MOR Series of DC/DC
converters operates from a standard 28 volt bus and offers a wide
input range of 16 to 40 VDC. Full operation over the military temper-
ature range, –55°C to +125°C, makes the MOR Series an ideal
choice for military, aerospace, space, and other high reliability appli-
cations. In compliance with MIL-STD-704D, the converters will with-
stand transients of up to 50 volts for up to 120 milliseconds. Use
Interpoint’s FME28-461 EMI filter to pass MIL-STD-461C, CE03
requirements.
The MOR Series converters incorporate a single-ended forward
topology which uses a constant frequency Pulse Width Modulator
(PWM) current mode control design and switches at 550 kHz,
nominal. The converters also provide short circuit protection by
restricting the current to 125% of the full load output current. All
models offer two inhibits, one referenced to input common and one
referenced to output common. A remote sense function is available
on single output models.
Using the trim function, the MOR Series can provide any output from
2 to 33 VDC. For example, trimming the two 15 volt outputs of the
15 dual (MOR2815D) to 14 volts, and then stacking the outputs will
provide a 28 volt output. See Figure 11.
