PM6670AS

Pin settings

7/54

VCC

+5 V Low-side gate driver supply. Bypass with a 100 nF capacitor to PGND.

CSNS

Current Sense Input for the switching section. This pin must be connected

through a resistor to the drain of the synchronous rectifier (RDSon sensing)

PHASE

Switch Node Connection and return path for the High-side Gate Driver.

HGATE

High-side Gate Driver Output

BOOT

Bootstrap Capacitor Connection. Positive supply input of the High-side Gate

Driver.

LDOIN

Linear Regulator Input. Connect to VDDQ in normal configuration or to a

lower supply to reduce the power dissipation. A 10

µF bypass ceramic

capacitor is suggested for noise rejection enhancement. See Device

Description section for more details.

VTT

LDO Linear Regulator Output. Bypass with a 20

µF (2x10 µF MLCC) filter

capacitor.
