2010.5.7
MPD5D01*S Specification
7
9. 2. 3 Low Voltage Protection
Output halts in latch-up mode after 500msec(typ) mask time while output voltage is below the value of
low voltage protection specified in 9.1.clause with failure of controller circuit or over load condition.
Output will re-start after input turns off for Min.1 second with input voltage less than 5V.
9. 2. 4 Remote On/Off Control
Start and halt is possible with a control signal.
While the control signal stops output from DC-DC Converter, alarm output does not send any signal.
Start : RC is open or connected to-Vin.
Halt : RC is connected to +Vin.
9. 2. 5 Alarm Output
ALM pin is down to the same voltage level of-Vin pin and sends an alarm signal. (open-drain output)
Sink current in ALM pin is Max.20mA.
It is possible to halt all of the connected DC-DC Converters when any one is halted with over voltage
protection or low voltage protection, with connecting all ALM pins for the application of multiple
operation with plural DC-DC converters.
The maximum number connecting DC-DC Converters is (one this product is counted as two) 20pcs
for the purpose of halting all DC-DC Converters connected with ALM pin each other. When the other
series are connected to this series for multiple operation, please count one this product as two.
Also please contact us when more than 20pcs.
9. 2. 6 Synchronous Turn-on/off
ALM pin is down to the same voltage level of-Vin pin and sends an alarm signal. (open-drain output)
Sink current in ALM pin is Max.10mA.
It is possible to halt all of the connected DC-DC Converters when any one is halted with over voltage
protection or low voltage protection, with connecting all ALM pins for the application of parallel/
multiple operation with plural DC-DC Converters.
The maximum number connecting DC-DC Converters is 10pcs for the purpose of halting all DC-DC
Converters connected with ALM pin each other.
Please contact us when more than 10pcs.
