表5-1. Pin Functions (continued)

I/O⁽¹⁾

DESCRIPTION

NAME

NO.

Positive input of the remote voltage sense of channel B. Connect this pin to VOUT_A at the

load for best voltage regulation. Do not let this pin float.

BVSP

Do not connect. This pin is connected to internal circuitry. Do not connect this pin to other signal

or voltage source. Connecting the pin to GND is recommended.

DNC

GND

—

Power ground of the device. Connect pins 1, 3, 13, and 15 to the bypass caps associated with

VIN. Connect pads 1, 3, 13, 15 to the PCB ground planes using multiple vias for optimal thermal

performance.

PMBCLK

PMBus serial clock interface. (Open Drain)

PMBDAT

I/O

PMBus bi-directional serial data interface. (Open Drain)

PMBus bi-directional ALERT pin interface. (Open Drain)

PMBALERT

Active low RESET input that resets the output voltage to its programmed BOOT voltage. This

pin requires a pullup resistor.

RESET

VIN

Input voltage. These pins provide voltage to the power conversion stages of the module.

Connect these pins to the PCB VIN planes using multiple vias for optimal thermal performance.

Output voltage of channel A. Connect these pins to the output A load. Connect external bypass

capacitors between these pins and GND pins 1, 3, and 13.

VOUT_A

VOUT_B

Output voltage of channel B. Connect this pin to the output B load. Connect external bypass

capacitors between this pin and GND pin 15.

(1) G = ground, I = input, O = output
