Description
Chip Enable pin, active high (internal pullup current source). By connecting this pin to GND, the switching operation
of the controller will be stopped.
Ground Connection
Output voltage monitoring input. This pin must be connected to the regulated output node as a feedback to on?chip
control circuitry. V OUT is internally connected to the on?chip voltage divider that determines the output voltage level.
