... Larger values improve noise rejection and load transient response. Reset Delay Time Select Selection of the NCV8769yz devices and the state of the DT pin determines the available Reset Delay times. The part is designed for use with DT tied to ground or OUT, but may be controlled by any logic signal which provides a threshold between 0 ...

... GND printed circuit board traces should wide as possible. When the impedance of these traces is high, there is a chance to pick up noise or cause the regulator to malfunction. Place external components, especially the output capacitor, as close as possible to the NCV8769 and make traces as short as possible. Reset Reset Delay Time Threshold ...
