UGATE2 (Pin1)
Connect this pin to the gate of an external MOSFET.
This pin provides the drive for the regulator’s pass tran-
sistor .
PHASE1 , PHASE2 (Pin26 and 2)
Connect the PHASE pins to the respective PWM
converter’s upper MOSFET source. These pins are
used to monitor the voltage drop across the upper
MOSFETs for over-current protection .
NC (Pin 3,4,5,6,7,20)
No connection.
PGOOD (Pin8)
PGOOD is an open collector output used to indicate
the status of the output voltages. This pin is pulled
low when the synchronous regulator output is not within
±
10% of the DACOUT reference voltage or when any
of the other outputs are below their under-voltage
thresholds .
OCSET1 , OCSET2 (Pin23 and Pin9)
Connect a resistor (R
) from this pin to the drain of
the respective upper MOSFET. R
, an internal
200
μ
A current source (I
OCSET
) , and the upper
MOSFET’s on-resistance (r
) set the converter
over-current (OC) trip point according to the following
equation :

FB2 (Pin10)
This pin provides the feedback for the non-synchro-
nous switching regulator. A resistor driver is con-
nected from this pin to vout2 and GND that sets the
output voltage. The value of the resistor connected
from Vout2 to FB2 must be less than 100
.
V5 (Pin11)
5V supply voltage. A high frequency capacitor (0.1
to 1uF) must be placed close to this pin and con-
nected from this pin to the GND plane for noise free
operation.
SS (Pin12)
This pin provides the soft start for the 2 switching
regulators. An internal resistor charges an external
capacitor that is connected from 5V supply to this pin
which ramps up the outputs of the switching regula-
tors , preventing the outputs from overshooting as well
as limiting the input current. The second function of
the Soft Start cap is to provides long off time for the
synchronoud MOSFET during current limiting .
FAULT (Pin13)
This pin has dual function. It acts as an output of the
OVP cicuitry or it can be used to program the fre-
quency using an extermal resistor. When used as a
fault detector , if any of the switcher outputs exceed
the OVP trip point , the FAULT pin switches to 12V
and the soft start cap is discharged. If the FAULT pin
is to be connected to any external circuity , it needs
to be buffered as shown in the application circuit .
FB4 (Pin14)
APW3007-12 : NC
This pin provides the feedback for the internal LDO
regular that its ourpur is Vout4.
VSEN2 (Pin15)
This pin is connected to the output of the I/O switch-
ing regulator. It is an input that provides sensing for
the Under/Over voltage circuitry for the I/O supply as
well as the power for the internal LDO regulator .
VOUT4 (Pin16)
APW3007-12 : NC
Functional Pin Description
This pin is the output of the internal LDO regulator.
