MPQ4569―75V, 0.3A, SYNCHRONOUS STEP-DOWN CONVERTER

PIN FUNCTIONS

Pin #

QFN-10

(3mmx3mm)

Pin #

SOIC-8

Name

Description

Ground. Connected the output capacitor as close as possible to avoid

high-current switch paths.

GND

Input Supply. Requires a decoupling capacitor to ground to reduce

switching spikes.

Enable Input. Pull this pin below the low threshold to shut the chip down.

Pull it above the high threshold enables the chip. Float this pin to shut the

chip down.

VREF

Bonding

Reference Voltage Output, for QFN-10 (3mmx3mm) package only.

Feedback Connected to the tap of an external resistive divider between

the output and GND. Sets the regulation voltage when compared to the

internal 1V reference.

Soft-Start Control Input. Connect a capacitor from SS to GND to set the

soft-start period.

Open Drain Power Good Output. “HIGH” output indicates VOUT is higher

than 90% of reference. POK is pulled down in shutdown, for QFN-10

(3mmx3mm) package only

Bonding

POK

BIAS

BST

Controller Bias Input. Supplies current to the internal circuit when

V_BIAS>2.9V.

Bootstrap. Positive power supply for the internal floating high-side

MOSFET driver. Connect a bypass capacitor between this pin and SW

pin.

Switch Node.
