An inhibit function is provided on MHE/MLP Series converters to
allow power shutdown and startup from a logic input. The unit is
inhibited when the inhibit input pin (pin 2) is connected to the input
common (pin 10). The open circuit voltage of the inhibit pin is 8 to
10 VDC for 12 V input models or 11 to 13 VDC for 28 V input
models. During inhibit, the input inhibit pin must sink approximately
1 mA. In the inhibit mode, converter output drops to less than 1 V
and the input current is typically 8 mA.
DESCRIPTION
The MHE Series™ and the MLP Series™ DC/DC converters offer
the high efficiencies associated with switching regulators, yet have
full isolation and the excellent regulation typical of linear regulators.
No external components are required for operation. MHE Series and
MLP Series converters are built using thick-film hybrid technology,
and are sealed in metal packages for military, aerospace, and other
high-reliability applications. Unscreened models are solder sealed
Automatic current limiting circuitry protects the MHE/MLP Series
converters against short circuits.
and are guaranteed to pass a gross leak test (maximum leak rate of
-3
1
x 10 atm.-cc/sec). Environmentally screened models are
hermetically sealed and are screened as described in Section C2.
MHE/MLP Series converters are rated to operate at full load up to a
case temperature of 85°C, with the output power derated linearly to
zero at 115°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 material
(PCB, copper sheet, heat sink, etc.) should be brought into contact
with the converter’s baseplate.
The MHE Series and MLP Series converters are pulse-width modu-
lated switching regulators operating in the forward mode, with a
nominal switching frequency of 125 to 140 kHz. Isolation is achieved
through the use of a transformer in the forward power circuit, and an
optocoupler is used in the feedback/control loop. The full load output
power is available over the full input voltage range. Short-term tran-
sients of 50 volts will not impair normal operation for 28 volt input
models.
When the MHE/MLP Series converters are used in applications
requiring full power operation for extended periods of time, or in
shock and vibration environments, it is highly recommended that the
flange-mount option be used. This option provides improved thermal
transfer capabilities as well as a mechanically secure mounting
configuration.
The efficiency is typically greater than 80% over the entire input
voltage range and from approximately 25% of full load to full load.
This feature makes the MHE/MLP Series converters ideal for either
battery or aircraft power applications.
