Other Parts Discussed in Thread: TPS62160
Have tried Eval board for the TPS62160
Board has divider R1 (1.21M) and R2 (383k) and supposed to hold 3.3V regulated output with wide input voltage 4 - 12 V
Was working OK.
When I have tried to change the resistors to R1 ( 562K) and R2 ( 180K) the output is not regulating any more and seems the controller is not working correctly - no regulation at the output any more.
The FB pin show 1.15V instead of 0.8V per divider values.
My questions are:
Does it require specific ratio of the resistors values and smaller ones will not work?
Does use of the smaller resistors can lead to the controller damage?
The current load I am trying is under 500 mA ( supposed to hold 1 A)
Thank you for the help.
