Other Parts Discussed in Thread: LM25184, LM5155, LM5156
Hello,
We would like to use LM25184-Q1 in our fly back design.
specification :
Input voltage: Min :12V , Normal :15v ,max :17V
Output voltage :15V 1A and 7V .25A
Inductance: 20uH, turns ratio
We have used "LM25183 and LM25184 Quickstart Design Tool (Rev. A)" to design the circuit.
Qn 1.For the above specification what would be the peak input current? As per the data sheet the equation for peak current calculation is given below.
As per this calculation the input current comes above 4.1A.Is it possible with LM25184 IC? because the internal mosfet is rated for 4.1A only.
Qn 2:What is the maximum power dissipation capability of the IC LM25184?
Qn 3: what would the temperature rise and thermal dissipation capability of the IC.
Kindly let us know whether we can proceed with the above specification.
Thank you
