DESCRIPTION

Interpoint’s MK200™ Series DC/DC converters deliver up to 200

watts of output power from an industry standard half-brick package.

The converters operate from -55°C to +125°C to satisfy the require-

ments of military, aerospace, and other high-rel applications. As

many as 5 single output converters may be paralleled for up to 900

watts of output power. The wide input voltage range of 19 to 40 VDC

provides full output power, while an extended input range of 16 to 40

VDC is available with derated output power operation from 16 to 19

VDC. Single and dual models deliver outputs of 5, 12, 15, ±12, or

±15 VDC.

EMOTE

ENSE AND

RIM

Remote sense terminals can be connected directly to your load to

compensate for line loss at high power (see Figure 3). All models

also have a trim function to adjust the output voltage. On dual

models, Vout2 is the adjustable output. The output voltage can be

adjusted down to as low as 60% or up to as high as 110%. Refer to

Figures 6 and 7 for connection diagrams and to Table 1 and 2 for

resistor values.

NHIBIT AND

YNCHRONIZATION

The inhibit and synchronization terminal (pin 4) can be used to

synchronize the MK200 Series converters to a system clock or

another converter. It can also be used to inhibit the converter. Pin 4

is referenced to input common and inhibited through an open

collector interface. When inhibited, the converter’s input current is

typically 15 mA while the inhibit terminal draws 1 mA or less. Multiple

units can be synchronized to enhance your system’s performance.

Refer to Figure 4 for connection diagram and notes.

ONVERTER

ESIGN

The MK200 Series of DC/DC converters combines dual-

phase/phase-shifted technology with a single-ended forward

conversion topology. This technology boosts power output without

increases in size and greatly reduces output noise while enhancing

the power density and efficiency of the converter. Packaged in one

module, two converters with parallel power paths operate at the

same frequency but are phase shifted from each other by 180°. The

result is a conversion frequency twice the switching frequency which

reduces switching noise and allows increased power density. The

dual converter design allows the dual models to be used in any

polarity:

• Two positive outputs

• Two negative outputs

• One negative and one positive output

The MK200 Series converters’ planar magnetics use printed

conductors instead of the traditional wire wound magnetics to elim-

inate errors that can occur in winding and provide 100% repro-

ducibility to ensure predictable operation of the converter. Film

capacitors on the input deliver another advantage with their low

ESR (Equivalent Series Resistance) and extremely low ESL

(Equivalent Series Inductance).

ROTECTION

EATURES

Protection features include soft start, undervoltage lockout and short

circuit protection. By controlling the start-up time, soft start mini-

mizes overshoot and large start-up current draw. Undervoltage

lockout, which typically occurs at 12 VDC, prevents possible

“hiccup” operation at low input voltages. Short circuit protection

limits short circuit current to a maximum of 190% of full load output

current.

ACKAGING

Six-sided metal construction provides EMI shielding and heat dissi-

pation in the industry standard half-brick package of 2.405 x 2.285

x 0.465 inches (61.09 x 58.04 x 11.81 mm). Internal silicon compo-

nents are hermetically sealed.

OISE

ANAGEMENT

Reduced switching noise and internal filtering combine to reduce

input ripple to as low as 65 mA peak to peak and output ripple to as

low as 25 mV peak to peak. Audio rejection is typically 35 dB.
