Applications Information
Thermal Considerations
The graph below in figure 4, gives details for the power derating of the AP8800AWT. This assumes the device to be mounted
on a 25x25mm PCB with 1oz copper standing in still air.
Soft-start
An external capacitor from the CTRL pin to ground will provide soft-start delay, by increasing the time taken for the voltage on
this pin to rise to the turn-on threshold and by slowing down the rate of rise of the control voltage at the input of the
comparator. The soft-start time is 0.5ms/nF.
