PIN FUNCTIONS

QFN2x3

Pin #

Name Description

1

VMAX

Internal Supply. A 2.2nF ceramic capacitor is required for decoupling. Place this

capacitor as close to the pin as possible.

2

STRG Connect to storage capacitor for energy storage and release operation.

3

Open drain output to indicate input power availability.

4

FB1

Feedback to set storage voltage.

5

GND

System Ground. This pin is the reference ground of the regulated output voltage. For

this reason care must be taken in PCB layout.

6

N/C

The pin should not be connected.

7

Open drain output to indicate storage voltage availability.

8

FB2

Feedback to set release voltage.

9

VIN

Supply Voltage. The MP6302 operates from a +4.2V to +18V input rail. Input decoupling

capacitor is needed to decouple the input rail.

10

BST

Bootstrap. A capacitor and a resistor in series connected between this pin and DC/DC

converter’s SW node is required to charge storage capacitor.
