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.
REMOTE SENSE AND TRIM
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.
INHIBIT AND SYNCHRONIZATION
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.
CONVERTER DESIGN
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:
PROTECTION FEATURES
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.
• 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).
PACKAGING
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.
NOISE MANAGEMENT
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.

Notes for Connections
Trim to Decrease Voltage
Trim to Increase Voltage
1. Sense: All connections should be made as close to the load as possible
for optimum load regulation. When sense is not used, the sense terminals
must be connected to their respective output terminals (pin 7 to pin 6 and
pin 9 to pin 10).
4
FIGURE 6: SINGLE OUTPUT TRIM CONNECTION
2. Inhibit and Synchronization: Inhibit/sync in (pin4) and sync out (pin 2) are
referenced to input common (pin 1). Referencing either of these pins to
any other point could result in damage to the converter. To synchronize
the converter, AC couple an 8V peak pulse, 20% duty cycle, sync signal
through a 2200 pF capacitor. The converters sync on the positive edge of
the pulse.
3. Paralleling: Up to five single output converters may be paralleled. Sense
connections should be made as close as possible to the load for optimum
load regulation.
4. Trim: All connections should be made as close to the load as possible for
optimum load regulation. When increasing the output voltage, do not
exceed the maximum output power rating. When decreasing the output
voltage, do not exceed the maximum output current rating. On dual output
models, only Vout2 can be trimmed. Minimum Vout2 is 10 VDC. When
trim pin is not used, leave unconnected.

CAUTION
Heat from reflow or wave soldering may damage
the device. Solder pins individually with heat
application not exceeding 300°C for 10 seconds
per pin. Due to the high conductivity of the pins,
a high power soldering iron is recommended to
meet time and temperature requirements.
Overheating may cause the solder attach to
reflow and loosen the pins.
