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.

D 2/18 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 +VOUT pin is the positive output, with respect to VOUT RETURN. 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.
