C OSC : External capacitor C OSC from this pin to ground sets
the operating frequency.
RUN/SS: Combination of Soft-Start and Run Control In-
puts. A capacitor to ground at this pin sets the ramp time
to full output current. The time is approximately 1.25s/ μ F.
Forcing this pin below 1.5V causes the device to shut
down. (See Applications Information section for quiescent
current note.) In shutdown all functions, including INTV CC ,
are disabled. Latchoff overcurrent protection is also in-
voked via this pin as described in the Applications Infor-
mation section.
I TH : Error Amplifier Compensation Point. The current
comparator threshold increases with this control voltage.
Nominal voltage range for this pin is 0V to 2.4V.
FCB: Forced Continuous/Synchronization Input. Tie this
pin to ground for continuous synchronous operation, to a
resistive divider from the secondary output when using a
secondary winding or to INTV CC to enable Burst Mode
operation at low load currents. Clocking this pin with a
signal above 1.5V P–P disables Burst Mode operation but
allows cycle-skipping at low load currents and synchro-
nizes the internal oscillator with the external clock. The
FCB pin must not be driven when the device is shut down
(RUN/SS pin low).
SGND: Small-Signal Ground. All small-signal components
such as C OSC , C SS , the feedback divider plus the loop com-
pensation resistor and capacitor(s) should single-point tie
to this pin. This pin should, in turn, connect to PGND.
