Pin Descriptions

NAME

FUNCTION

Output of the buffer leading to the error amplifier. Used for external modifications of

the compensation network.

COMP

External feedback voltage input. Option for programming the output voltage with a

XFB

resistor divider on V_OUT

Remote voltage sense input. Connect this pin to the load voltage at the point to be

regulated.

VSENSE

EAIN

EAOUT

ENABLE

Input of the error amplifier for external modifications of the compensation network.

Output of the error amplifier for external modifications of the compensation network.

Enable input. An input high enables operation. An input low disables operation.

NO CONNECT – Do not electrically connect this pin to PCB. See Note 5.

Over-Voltage set-point input. When using an external voltage divider and the XFB pin. When

VS0, VS1 and VS2 are left OPEN or pulled high, an additional voltage divider separate from

the XFB pin is required to set the OVP set-point. In this mode, the OVP function is disabled if

this voltage divider is not present.

XOV

PGND

Power ground for the power stage circuits.

VOUT

Voltage and power output.

VDRAIN

PGND

Test point between the power FETs and Inductor.

Power ground for the power stage circuits.

NO CONNECT – Do not electrically connect this pin to PCB. See Note 5.

Power voltage input for the power stage circuits.

PVIN

VS2

ROCP

VS1

Voltage select line 2 input. See Table 1.

Over-Current trip point adjust input. Used for adjusting the OCP trip point.

Voltage select line 1 input. See Table 1.

AVIN

AGND

VS0

Analog voltage input for the controller circuits.

Analog ground for the controller circuits.

Voltage select line 0 input. See Table 1.

POK

Power OK is an open drain transistor for power system state indication.

Soft-Start node. A capacitor is connected between this pin and AGND.

NOTES:

5. This pin is used for engineering test purposes and reserved for future use. Solder, but do not electrically connect this pin to

the PCB.
