We have an requirment of power supply module board mounted for our design Application. The requirement specification is attached in this forum.We need your help regarding for this design. Awaiting for your reply.
Otherwise any Specific IC (DC to DC converter IC) is there for the particular specification please inform me, and also I need a design application circuit and simulation report
74VDC,8A ( 65-95V Dc is variable) with Isolation voltage withstand 1500VDC between the circuits and the chasis for a minimum of 1 minute with no more than 1mA leakage
POT for Output Voltage Adjustment
DC/DC Board Mount
Any Other Special Features Required
1. Output over voltage protection 2. Output over current protection 3. Over temperature protection 4. Input ON/OFF control (Negative/Possitive logic) 5. Military grade
1. Output over voltage protection 2. Output over current protection 3. Over temperature protection 4. Input remote ON/OFF control (Negative/Possitive logic) 5. Military grade
TI has no power military grade or any power modules which meet your requirement s.
We are using LM3488MM IC for booster purpose. We are setting the output voltage 13.5 @ 3A. and attached the design circuit also.
The problem is when we are increasing the input voltgae 6 to 8.3V. The ouput voltage Remains constant @ 13.5V at no load condition.
If I give output load 100mA the output voltage drops at that time the input voltage is 6 to 7.4V. That is the switcher not switching proberly. The input voltage comes at output voltage. When I am increasing Input voltage above 7.4V the output voltage remains constnt at 13.5 V @100mA load.
I need what is the problem in the input voltage 6 to 7.4V when iam giving minimum load.
If it is design problem please rectify and tell me
