NAME

I/O

FUNCTION

1,2,3,

79-101

VOUT

Regulated

Output

Regulated output voltage. Decouple to PGND with appropriate filter capacitors

RVSET

Analog

I/O

A resistor from RVSET to AGND; and can be used to program the VOUT set-point.

Using 1% tolerance or better resistor. See Table 8 and Table 9 for more

information.

RTUNE

Analog

I/O

A resistor from RTUNE to AGND; and can be used to tune the transient

compensator for the amount of output capacitance. Using 1% tolerance or better

resistor. See Table 10 and

Table 11 for more information.

VINSEN

Analog

Input

Single-ended input voltage sense (relative to AGND).

ADDR1

Analog

I/O

A resistor from ADDR1 to AGND; and can be used to set the PMBus™ address. Use

a 1% tolerance or better resistor.

ADDR0

Analog

I/O

A resistor from ADDR0 to AGND; and can be used to set the PMBus™ address. Use

a 1% tolerance or better resistor.

PWM

PWM signal test pin.

SYNC

Digital I/O PWM synchronization signal

POK

Digital I/O Power OK is selectable as a push-pull output or an open drain transistor for

power system state indication. See the Power OK description for details.

CTRL

Digital

Input

PMBus-compatible control pin with programmable functionality. CTRL should

never be left floating if enabled in Configuration. The default configuration is for

VOUT to be on with CTRL high (positive edge)

SALRT

Digital

Output

PMBus™ alert line.

SDA

Digital I/O PMBus™ serial data I/O.

SCL

Digital I/O PMBus™ serial clock input.

VDD33

Output

3.3V output of the internal LDO. May be used as pull-up supply for PMBus™ pins

and CTRL pin.

PGND

Ground

Power ground. Ground for MOSFET switches.

PVCC

Input

Supply

5.0V supply voltage for driver circuitry. Decouple to GND using a 2.2µF MLCC high

quality ceramic capacitor.

VCC

Input

Supply

5.0V supply voltage for analog circuitry.

67,68,

73-76

No connect. Do not connect to any signal, supply, or ground.

DGND

Ground
