Type

Description

N.C.

AT_FLAG

Open drain

The two-event detector should discern

between AF and AT classification

waveforms and outputs the AT_FLAG

(PD70200 only).

PGOOD

Open drain

After startup, a PGOOD flag is

generated in order to optionally inform

the application DC/DC converter that

the power rails are ready.

VAUX

Power

Auxiliary output voltage to VPNOUT. Can

be used for DC-DC startup for bootstrap

initiation.

VPP

Power

High voltage positive input, reference to

VPNIN and high voltage positive input,

reference to VPNOUT during capacitor

discharge.

EPAD

Connect to VPNIN. EPAD should be

connected to a large copper area for

improved thermal management.
