Other Parts Discussed in Thread: TPS5420, , TPS5410-Q1, TPS5410
Hi,
To reduce the size of our PCB we changed our output inductor and capacitor. The part number of inductor and capacitor is given below.
- O/p Inductor - XAL5050-223MLC - 22uH, 3.4 Irms @40deg
- I/p Capacitor - GRT21BC71E106KE13L - 10uF, 0805,X7S, 25V
- I/p Capacitor - GRM21BR61H475KE51L - 4.7uF, 0805, X5R, 50V
- Input Voltage - 28V DC.
- Output Voltage - 15V DC.
Issue : The above is our design specifications. In this above design we have a problem with this regulator while switching on TPS5420 drawing more current and IC is going bad. so kindly clarify the issues.
Thanks
