Other Parts Discussed in Thread: LM5069
Hi,
I am designing the LM5067 Application to limit the Inrush Current for my 48V Power Supply. The schematic as above. Design parameters as below:
+ Vin = 48V
+ I Limit = 2A
+ UVLO = 40V and OVLO = 60V
I consider 2 problem:
+ First: The circuit can work with +48V applied to VEE and GND applied to VCC via R3045? Because in the LM5607 datasheet, they used -48V to VEE and GND applied to VCC.
+ Second: The insertion time as my calculated in my circuit is 220ms with C_timer is 0.33uF. But in the case I used the TI Tool (www.ti.com/.../HOTSWAP-EFUSECALCULATORS), the value of Insertion Time is 1440ms and C_timer is 2.2uF, with the same design parameter. I think my circuit is wrong at some points but I don't know why...
Please help me to clearly understand 2 issues. Thank for any advances.
Frank,
