Product details

Description

Pin Symbol Description 1 CE Chip Enable Pin 1. The chip is enabled if a voltage which is equal to or greater than 0.9 V is applied.2. The chip is disabled if a voltage which is less than 0.3 V is applied.3. The chip will be enabled if it is left floating.2 FB PFM comparator inverting input, and is connected to off chip resistor divider which sets output voltage.
