COMP (Pin 1): Compensation Pin. This pin is the output of
the Error Amplifier and is made available for loop compen-
sation. It can also be used to adjust the maximum value of
the current sense clamp voltage to less than 1V. This pin
can source a minimum of 0.5mA (0.8mA typ.) and sink a
minimum of 2mA (4mA typ.)
FB (Pin 2): Voltage Feedback. This pin is the inverting
input of the Error Amplifier. The output voltage is normally
fed back to this pin through a resistive divider. The
noninverting input of the Error Amplifier is internally
committed to a 2.5V reference point.
6
I SENSE (Pin 3): Current Sense. This is the input to the
current sense comparator. The trip point of the compara-
tor is set by, and is proportional to, the output voltage of
the Error Amplifier.
R T /C T (Pin 4) : The oscillator frequency and the deadtime
are set by connecting a resistor (R T ) from V REF to R T /C T
and a capacitor (C T ) from R T /C T to GND.
The rise time of the oscillator waveform is set by the RC
time constant of R T and C T . The fall time, which is equal to
the output deadtime, is set by a combination of the RC time
constant and the oscillator sink current (8.2mA typ.).
