Pin description
Regular output
Current error amplifier input (current sense at higher voltage)
Current error amplifier input (current sense at lower voltage)
Stepdown feedback input. Connecting directly to this pin results in an output voltage of
1.235 V. An external resistive divider is required for higher output voltages. In this case:
Ground
Unregulated DC input voltage.
