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.

PIN FUNCTION DESCRIPTION
Pin No. NCP630A NCP630G Description
1 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.

resistors on the output. It main-
tains 1.216 V between itself and ground. Refer to Figure 1 for equation.
5 − Sense This pin is to be connected near the load for better regulation.
