description

Interpoint’s MHV Series™ of DC/DC converters offers a wide

input voltage range of 16 to 50 VDC and a choice of nine

different output voltage configurations comprised of single, dual

or triple outputs. The 3.3 volt single, 5 volt single and dual and

the triple output models will withstand transients of up to 80 volts

for up to 120 milliseconds while maintaining output voltages.

The 12 volt single and dual outputs will withstand transients up

to 75 volts and the 15 volt single and dual outputs will withstand

up to 60 volts for 120 milliseconds. The MHV Series operates at

15 watts of output power (10 watts for the 3.3 volt single output)

over the military temperature range of -55°C to +125°C while

maintaining low input and output noise.

inhibit FunCtion

The converter is enabled when the inhibit terminal is left uncon-

nected. When the inhibit terminal is pulled low (<0.8 V) the

converter shuts down, typically drawing 8.4 mA at 28 Vin or 15

mA at 50 Vin. Sinking current required is Vin / 3.3 K ohm.

synChronization FunCtion

Applying an external signal of 40% to 60% duty cycle and 490

to 710 kHz for singles and duals output models will synchronize

the converter to your system requirements. For triple output

models the external frequency range is 500 to 700 kHz. Free run

clock frequency is approximately 600 kHz. If not used, the sync

terminal must be left unconnected.

Converter Design

MHV Series DC/DC converters are switching regulators that use

continuous flyback conversion topology with a clock frequency

of approximately 600 kHz. MHV Series converters incorporate

two pulse width modulators (PWM) with one PWM phase shifted

180° from the other to create a dual phase/phase-shifted opera-

tion. Each of the PWMs operates at approximately one-half (300

kHz) of the clock frequency. This proprietary technology mini-

mizes input ripple and improves efficiency. On singles the output

ripple is reduced. Cross regulation is eliminated on dual output

models which are independently regulated and do not require

load balancing or minimum loading. On triple output models, this

design provides completely independent regulation with no cross

regulation effect between the main and auxiliary outputs and no

minimum loading is required on the main output.

trim

Single output converters feature a trim range of as low as 80%

to as high as 110% of Vout nominal, depending on the model.

To trim up, connect a resistor from output common (pin 4) to the

trim terminal (pin 3). To trim down, connect a resistor from the

positive output (pin 5) to the trim terminal (pin 3). See Figure 4

and trim tables for more information.

sCreening

The converters are offered with standard screening, “ES”

screening, or fully compliant to “883” MIL-PRF-38534 Class H

screening. Standard microcircuit drawings (SMD) are available.
