新人求教,客户需求一个反击变压器。参数如下,
Power handling of at least 15W at 125C
Input voltage range of 7.3-16Vdc
Fsw 250kHz
Primary inductance of 2.5uH (lower end of the tolerance band)
Turns ratio of 1:1.83:1.83:1.83:1.83 (one winding 7.5W, three
windings 2.5W each)
HV clearance of 5.6mm and reinforced insulation is required
between primary and secondary.
Clearance of 3mm between secondaries.
14mm or less height
Must fit on the attached footprint with the pinout specified
Must have AEC-Q and PPAP in time for SoP.
Here are some more details on the HV clearance/creepage requirements:
Working voltage is 450V
Hipot test is 4300VDC for 60 seconds
但是客户测试样品之后反应如下:
我想知道我该怎么调节结构、 |
