I am using Part # LM5085Q version in my application which is in a Automotive environment.
I want to know if I can substitute the p ch. mosfet given in the web bench design with anoither p ch. mosfet.
The mosfet in the web bench design is a SUM110P08-11 by Vishay Siliconix
The substitute part is IRFR5410PBF by International Rectifier.
My Spec's. on the design are as follows:
Input Voltages - 7V min. - 60V Max.
Output Voltage is - 6V and the current is 600mA
The actual load current is 300mA - 400mA that changes up and down every 3-4 seconds because of a varying load.
The Web Bench parameters of parts are as follows , that the design gave :
Cin - 10uF / 100V
Cout - ( 2 ) 22uF / 10V
Cvcc - 1uF / 16V
Cadj. and Radj. are - 1000pF / 50V and 2.55K ohms
Rsense is - .1 ohms
Cr and Rr are - 3300pF / 10V and 66.5K ohms
Cac - 10nF / 25V
Rfb1 and Rfb2 - 3.16K ohms and 12K ohms
D1 - BYS12-90-E3/TR by Vishay Semiconductor
L1 - MSS1048-224KLB by Coilcraft
Rt - 187K ohms
M1 - SUM110P08-11 by Vishay Siliconix which I want to substitute
