Pin Function
This pin is the connection between two build-in switches in the chip, which
should be connected to the external inductor. The inductor should be
connected to this pin with the shortest path.
Supply input. A minimum of 10F (RT5707) and 4.7F (RT5707A) ceramic
capacitor should be connected to this pin with the shortest path
Chip enable input pin. High level voltage enables the device while low level
voltage turns the device off. This pin must be terminated.
Device ground pin. This pin should be connected to input and output
capacitors with the shortest path.
Output voltage selection pin. This pin must be terminated.
Output voltage feedback pin. This pin should be connected close to the output
capacitor terminal for better voltage regulation. A minimum of 10F ceramic
capacitor should be connected to this pin with the shortest path.
Output voltage selection pin. This pin must be terminated.
Output voltage selection pin. This pin must be terminated.
