NCP392B Overview
123 4 A /EN OUT OUT PGND B VBUS _D OUT IN PGND C OVLO IN IN PGND (Top View) Figure 3. Pinout Table 1. NCP392 PIN Pin Pin Name Type A1 EN I/O Enable pin bar. The device enters in shutdown mode when this pin is tied to a high level. In this case the output is disconnected from the input. To allow normal functionality, the EN pin is tied low with internal pull down. This pin does not have an impact on the VBUS_DET. A2, OUT A3, B2
