Function
Input for synchronization of the
oscillator to an external frequency,
or output to synchronize multiple
devices.
The external timing components of
the ramp generator are attached to
this pin.
Error amplifier output and Pulse
Width Modulator (PWM) input for
loop stabilization network.
Non-inverting input of the error
amplifier.
Inverting input of the error amplifier.
The capacitor at this pin determines
the soft-start characteristic.
A low input voltage at POL will
activate the output EME.
POL is the input to a non inverting
Schmitt-trigger.
Output of the FET-driver.
Drain connection of the power FET.
Source connection of the power
FET.
C
buffer-capacitor and a current
limiting charging-resistor.
