VID0-3(pin20-23):
Voltage Identification code in-
put. These open collector compatible inputs are
used to program the output voltage as specified
in Table 1. Every pin has an internal pull up. If all
four pins are high or floating, the output voltage
and the 2.5V regulator are suspended and the
POWERGOOD is low.
VSS1(pin24):
ThispinhastobeconnectedtoVSS.
NOSKIP(pin25):
Pulse skipping mode control. A
high level (>2.4V) disables pulse skipping in low
load condition,a low level (>0.8V) enables it.
HSRC(pin26):
source connection. This pin provides the return
path forthe high side driver.

N-Channel
switch
HGATE(pin27)
: Gate driver output, high side N-
Channel switch. The driver internal impedance is
about 4
at VIN=12V.
HSTRAP(pin28):
Bootstrap capacitorpin. This pin
provide to supply the high side driver sinking the
current by the bootstrapcapacitor.
RSTRAP(pin29):
driver supply voltage. This pin could be con-
nected to REG5 to reduce the switching losses
due to the external mosfets gate capacitance.
This is useful to maintain an high efficiency at
light load.
Synchronous
rectifier
gate
RGATE(pin30):
Gate driver output, low side N-
Channel switch. The driver internal impedance is
about 3
at VIN=12V.
PWRGND(pin31):
Power ground. This pin has to
be connected closely
source in order to reduce the noise injected into
the IC.

POWER GOOD(pin32):
Open drain power good
output. This pin is pulled low if the output voltage
is not within
±
10% and the 2.5V output is lower
than 2.175V (-13%). The pin is pulled low also if
REG5, VPROG and VBG have not reached the
expected values. This test could be useful in an
assemblingfault condition
