10) Ground wiring pattern
When using both small-signal and large-current GND traces, the two ground traces should be routed separately but
connected to a single ground at the reference point of the application board to avoid fluctuations in the small-signal
ground caused by large currents. Also ensure that the GND traces of external components do not cause variations on
the GND voltage. The power supply and ground lines must be as short and thick as possible to reduce line impedance.
11) Thermal shutdown circuit
The IC incorporates a built-in thermal shutdown circuit, which is designed to turn off the IC when the internal
temperature of the IC reaches a specified value. It is not designed to protect the IC from damage or guarantee its
operation. Do not continue to operate the IC after this function is activated. Do not use the IC in conditions where this
function will always be activated.
