Pin Function Description
Current Limit. A resistor from this pin to ground sets the over current trip level.
Droop Control/Energy Star Mode Control. A resistor from this pin to ground
sets the amount of droop by controlling the gain of the current sense amplifier.
When this pin is pulled high to BYPASS, the slice 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.
