Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit

values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,

damage may occur and reliability may be affected.

Shutdown

Shutdown

This input is used to place the NCP630 into shutdown mode. The NCP630

is active when a voltage greater than 2.0 V is applied. The NCP630 will be

placed into a shutdown mode when a voltage less than 0.8 V is applied. If

left unused then connect the pin high.
