Recommended Operating Conditions (See Figure 2)

20

ILIM

Current Limit. A resistor from this pin to ground sets the over current trip level.

21

DROOP/E*

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 phase A drivers are turned off for

Energy-star operation.

22

ENABLE/SS

Output Enable/Softstart. A logic LOW on this pin will disable the output. An

10µA internal current source allows for open collector control. This pin also

doubles as soft start.

23

RT

Frequency Set. A resistor from this pin to ground sets the switching frequency.

24

VFB

Voltage Feedback. Connect to the desired regulation point at the output of the

converter.
