(1x) (2x)

Low Voltage Digital Input

ACMP3+

Analog Comparator 3

Positive Input

Analog

GND

Logic Ground. All GND, AGND0, AGND1, and PGND pins must be connected together externally.

IO1

General Purpose IO

Digital Input without

Schmitt Trigger

Push-Pull (1x) (2x)

Digital Input

with Schmitt Trigger

Open-Drain NMOS

(1x) (2x)

Low Voltage Digital Input

Open-Drain PMOS

ACMP0+

Analog Comparator 0

Positive Input

Analog

AGND1

Analog ground for internal control circuit. Connect this pin to Power GND plane on PCB. All GND,

AGND0, AGND1, and PGND pins must be connected together externally

DC_INT

DC/DC Converter Interrupt Output. INT is an Open-Drain, asserted logic high digital output that be-

comes asserted within TINT(HIGH) when an over-current condition has been detected at the output.

INT becomes deasserted within TINT(LOW) when the over-current condition no longer persists.

Manufacture test pin, do not connect

DC_VOSNS DC/DC Converter Input sense pin for output voltage

DC_SW

DC/DC Converter Switch Output. Connect this pin to an external, low DCR inductor – see Applications

Information for additional details

PGND

DC/DC Converter Power ground. Connect this pin to Power GND plane. All GND, AGND0, AGND1,

and PGND pins must be connected together externally

PGND

DC/DC Converter Power ground. Connect this pin to Power GND plane. All GND, AGND0, AGND1,

and PGND pins must be connected together externally

DC_VIN

DC/DC Converter Supply input. Connect a 10 µF (or larger) low ESR capacitor from this pin to Power

GND plane. Capacitors used at VIN should be rated at 10 V or higher. DC_VIN and VDD pins must be

connected together externally.
