DESCRIPTION

The efficiency is high over the entire input voltage range and from

approximately 25% of full load to full load. This feature makes the

converters ideal for either battery or aircraft power applications.

The MHL Series™ of DC/DC converters offers either ±12 or ±15 volt

outputs in a single package. MHL converters offer the high efficiency

and wide input range of switching regulators with excellent load and

line regulation. Input and output grounds are isolated from one

another and from case ground. No external components are

required for operation. The units are built using thick-film hybrid

technology and are sealed in metal packages for military, aero-

space, and other high-reliability applications. Unscreened models

are sealed with solder and are guaranteed to pass a gross leak test

An inhibit function is provided to allow power shut-down and start-

up from a logic input. An open circuit on the inhibit terminal produces

normal operation, and a low level disables the converter. Input

current in the inhibit mode is typically 20 mA. The converter features

a “soft-start” function which provides a controlled 20 millisecond

turn-on upon application of input power or inhibit release.

-3

(maximum leak rate of 1 x 10 atm.-cc/sec). Environmentally

screened models (/ES) are hermetically sealed with solder and will

pass a fine leak and gross leak test as described in Section C2.

An input filter is incorporated in the unit to reduce input reflected

ripple current. Both outputs are indefinitely protected against short

circuits to ground or to one another by automatic current limiting

circuitry. This feature adjusts the converter’s output current, indefi-

nitely maintaining it below approximately 125% of the rated

maximum during a full short circuit condition.

The MHL converters employ pulse-width modulated switching regu-

lator techniques in the forward mode, with

a nominal clock

frequency of 210 kHz. Isolation is achieved through the use of a

transformer in the forward power circuit and an opto-coupler in the

feedback/control loop. The full load output power (15 watts) is avail-

able over the input range of 4 to 8 VDC. Up to 14.3 watts can be

obtained from a single output up to a combined load of 15 watts.

The MHL Series of converters is rated to operate at full load at a

case temperature of 85°C, with the output power derated linearly to

zero at 115°C (0.5W/°C). Because of the unit’s high efficiency, heat

sinking requirements are minimized, but due consideration should

be given to removing self-generated heat when operating the device

at maximum ratings. To increase dissipation, heat conducting mate-

rial (PCB, copper sheet, heat sink, or Interpoint’s TMP accessory)

should be brought into contact with the converter’s baseplate.

_IN=5 V

When the MHL is used in applications requiring full-power operation

for extended periods of time, or in shock and vibration environ-

ments, it is highly recommended that the flange-mount case option

be used. This option provides improved thermal transfer capabilities

as well as mechanically secure mounting configuration.
