MODE/PLLIN (Pin 27/Pin 36): Force Continuous Mode,
BurstModeorPulse-SkipModeSelectionPinandExternal
Synchronization Input to Phase Detector Pin. Connect this
pin to SGND to force both channels in continuous mode of
operation.ConnecttoINTVCCtoenablepulse-skipmodeof
operation. Leaving the pin floating will enable Burst Mode
operation. A clock on the pin will force the controller into
continuousmodeofoperationandsynchronizetheinternal
oscillator with the clock on this pin.
FREQ (Pin 29/Pin 38): This pin sets the frequency of the
internal oscillator. A constant current of 7.5µA is flowing
out of this pin and a resistor connected to this pin sets
its DC voltage, which in turn, sets the frequency of the
internal oscillator.
RUN1, RUN2 (Pins 30, 11/Pins 1, 17): Run Control
Inputs. A voltage above 1.2V on either pin turns on the IC.
However, forcing either of these pins below 1.2V causes
the IC to shut down the circuitry required for that particular
channel. There are 1µA pull-up currents for these pins.
Once the RUN pin rises above 1.2V, an additional 4.5µA
pull-up current is added to the pin.
pin FuncTions (QFN/TSSOP)
SENSE1+, SENSE2+ (Pins 31, 10/Pins 2, 16): Current
Sense Comparator Inputs. The (+) inputs to the current
comparators are normally connected to DCR sensing
networks or current sensing resistors.
SENSE1, SENSE2(Pins 32, 9/Pin 3, 15): Current Sense
ComparatorInputs.The(–)inputstothecurrentcompara-
tors are connected to the outputs.
SGND (Pin 33/Pin 8): Signal Ground. All small-signal
components and compensation components should
connect to this ground, which in turn connects to PGND
at one point. Pin 33 is the Exposed Pad and available for
QFN package.
SGND (Exposed Pad Pin 33/ Exposed Pad Pin 39): Signal
Ground.MustbesolderedtoPCB,providingalocalground
for the control components of the IC, and be tied to the
PGND pin under the IC.
PGND1, PGND2 (NA/Pins 32, 26): Power Ground Pin.
Connect this pin closely to the sources of the bottom
N-channel MOSFETs, the (–) terminal of CVCC and the (–)
terminal of CIN.
