Pin Functions (continued)

PIN

DESCRIPTION

NAME

NO.

RTSEL

10

I

This pin can be used to adjust the switching frequency to 1 MHz without the need for an external

resistor. Connect this pin to AGND to adjust the frequency to 1 MHz. Otherwise, leave this pin

floating.

SENSE+

22

I

Remote sense connection. This pin must be connected to VOUT at the load or at the device pins.

Connect the pin to VOUT at the load for improved regulation.

SS/TR

25

I

Slow-start and tracking pin. Connecting an external capacitor to this pin adjusts the output voltage

slow-start ramp above its 4.1 ms default setting. A voltage applied to this pin allows for tracking and

sequencing control.

VADJ

24

I

Connecting a resistor between this pin and AGND adjusts the output voltage.

VBSEL

7

I

Selectable internal bias supply. For output voltages

≥ 4.5 V, connect this pin to VOUT. For output

voltages < 4.5 V, connect this pin to AGND.

VERSA-

COMP

23

I

Connects to internal compensation network. This pin can be left floating or connected to the VADJ

pin to select the proper compensation depending on the output voltage.

VOUT

13, 14, 15,

16, 17, 18,

43

O

Output voltage. These pins are connected to the internal output inductor. Connect these pins to the

output load and connect external bypass capacitors between these pins and PGND close to the

device.

(1)

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings

only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended

Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2)

The maximum voltage that can be applied to these pins is 30 V or PVIN, whichever is less.

(3)

See temperature derating curves in the Typical Characteristics section for thermal information.
