DROOP/E*
Droop Control/Energy Star Mode Control.
sets the amount of droop by controlling the gain of the current sense amplifier.
When this pin is pulled high to BYPASS, the phase A drivers are turned off for
Energy-star operation.
Output Enable/Softstart.
A logic LOW on this pin will disable the output. An
internal current source allows for open collector control. This pin also doubles as
soft start.
Frequency Set.
A resistor from this pin to ground sets the switching frequency.
Voltage Feedback.
Connect to the desired regulation point at the output of the
converter.
