Description
Bucket capacitor 1. Connect this pin to the negative terminal of the bucket (flying) capacitor.
Ground.
Enable. Enables the IC when high. Disables the IC when low and enters shutdown mode.
No internal pull-up or pull-down; this pin should not be left floating.
Bucket capacitor 1. Connect this pin to the positive terminal of the bucket (flying) capacitor.
Power input.
Regulated 5V output.
Bucket capacitor 2. Connect this pin to the positive terminal of the bucket (flying) capacitor.
Bucket capacitor 2. Connect this pin to the negative terminal of the bucket (flying) capacitor.
