NCP349 General Description

Pin No. Symbol Function Description 1, 7 IN INPUT Input Voltage Pins. These pins are connected to the Wall Adapoter (AC *DC, Vbus ..). A 1 mF low ESR ceramic capacitor, or larger, must be connected between these pins and GND, as close as possible to the DUT. The two IN pins must be connecte.
