Pins descriptions

Pin #

Name

Function

1

N.C.

Not internally connected.

2

GND

Ground connection. Connect to PCB ground plane.

3, 4

N.C.

Not internally connected.

5

PGOOD

Power Good output flag: the pin is open drain and it is forced low if the

output voltage is lower than 90 % of the programmed voltage. If not used, it

can be left floating.

6

VBIAS

Input bias supply. This pin supplies the internal logic to drive the power

N-channel MOSFET that realize the voltage conversion. Connect directly to

7EN

Enables the device if a voltage higher than 1 V is applied.

When pulled low, the device is in low-power consumption: everything inside

the controller is kept OFF.

See Section 6.2 for details about EN signal and power sequencing.

8 to 10

VIN

Power supply voltage. This pin is connected to the drain of the internal

N-channel MOSFET.

11 to15

N.C.

Not internally connected.

16 to 18

VOUT

Regulated output voltage. This pin is connected to the source of the

internal N-mos. MLCC capacitor are supported. Filter to GND with
