DESCRIPTION:
The MSK7010RH is a 10W radiation hardened fully isolated DC to DC converter. The MSK7010RH simplifies design of
high efficiency radiation hardened power supplies and requires a minimum amount of board space. High efficiency minimizes
input bus loading. User selectable over current fault response allows the designer to select between latching power off
or constant current output in the event of an overload. The MSK7010RH is hermetically sealed in a 7 pin powerpack with
straight or formed leads and is specifically designed for space/satellite applications.

APPLICATION NOTES
TYPICAL APPLICATION CIRCUIT #1
PIN FUNCTIONS
+VIN - Connect +VIN to the primary power bus positive rail. Input capacitors are
typically not required if the input bus impedance is less than 11Ω below 30kHz.
VIN RETURN - Connect VIN RETURN to the primary power bus negative rail.
CASE
- Provides an electrical connection to the device
package only. This pin is isolated from all internal circuitry.
LATCH ENABLE/RESET - The latch pin determines the behavior of the
converter during an over current event. Open circuit this pin to allow the
converter to latch off the output if an over current condition is detected. Connect
a capacitor between the LATCH ENABLE/RESET pin and VIN RETURN to
delay the latch off of the output. The value of the capacitance determines the
delay time between the onset of an over current event and output shutdown.
See the typical performance curves section for additional information. Toggle
this pin to VIN RETURN to reset the latch and restart the converter. Connecting
the latch pin to VIN RETURN will disable the latch feature and the converter
will behave as a constant current source during an over current event.
Active high shutdown and latch reset.
10mS latch off delay.
SHUTDOWN - Pull this pin to VIN RETURN (typically <2.8V) to put the
converter in a low power shutdown state, disabling the output and most
internal circuitry. Open or pull this pin above 10V to enable the converter.
TYPICAL APPLICATION CIRCUIT #2
+VOUT - The +VOUTpin is the positive output, with respect to VOUTRETURN.
Output capacitors are not typically required, however high frequency ceramic
capacitance mounted near the load are recommended to support fast load
transients. Additional bulk capacitance connected to this pin is acceptable.
However, excessive output capacitance may negatively affect dynamic
response. The output is floating and a negative load voltage can be obtained
by grounding +VOUT and connecting the load from VOUT RETURN to ground.
VOUT RETURN - The VOUT RETURN pin is the NEGATIVE
OUTPUT, it is the load current return pin when the MSK7010 is
connected as a positive power source. Connect to the load negative
terminal with low impedance traces to minimize load regulation error.
TOTAL DOSE RADIATION TEST PERFORMANCE
Radiation performance curves for TID testing will be generated for
all testing performed by MSK. These curves show performance
trends throughout the TID process and can be located in the
MSK7010RH radiation test report. The complete test report will be
