Other Parts Discussed in Thread: TPS62870,
Dear Sir/Madam:
Now I use TPS62870 in my application , my design current is 2A~6A , but realy it noly can output 0.5A , when the current exceeds 0.6A , the output volotage is drop a lot . and I can hear " ci ci .." the sound the inductor makes . the schematic is as below:(figure 1)
later i modfed some parameters as figure 2 , but same result.
what is the reason for this?
BG!
