PWM oscillator pin
Connect to ground with a capacitor to
set oscillation frequency.
PWM output
Open collector output (Darlington
connection). In direct PWM mode (LIM
pin Low) the output is an FG Schmitt
output.
Output current detector pin
Connect to ground via a lower resistor.
Sets maximum output current I
OUT =
0.5/Rf.
Output pin (for external bottom-side
transistor drive)
Performs duty cycle control in direct
PWM mode (LIM pin Low).
Output pin (for external bottom-side
transistor drive) .
Open collector output.
