The ZCD Pin ensures critical conduction mode. ZCD monitors the voltage on the auxiliary winding,
during the demagnetization phase of the transformer, comparing it to an internal reference. The
ZCD sets the latch for the output driver.
The Current Sense Pin monitors the current in the power switch by measuring the voltage across
a resistor. Leading Edge Blanking is utilized to prevent false triggering. The voltage is compared to
a resistor divider connected to the Voltage Feedback Pin. A 110 mV voltage off--set is applied to
compensate the natural optocoupler saturation voltage.
The Voltage Feedback Pin is typically connected to the collector of the optocoupler for feedback
from the isolated secondary output. The Feedback is connected to the V
providing bias for the external optocoupler.

The Frequency Clamp Pin ensures a minimum off--time value, typically 6.9 ms. It prevents the
MOSFET from restarting within a fixed (33364D1) or adjustable (33364D) delay. The minimum
off--time is disabled in the 33364D2. Therefore the maximum switching frequency cannot exceed
1/(T
This pin is the ground for the internal circuitry excluding the gate drive stage.
This pin is the ground for the gate drive stage.
The gate drive is the output to drive the gate of the power MOSFET.
Provides the voltage for all internal circuitry including the gate drive stage and V
Undervoltage Lockout with hysteresis.
The Line Pin provides the initial power to the V
current source, eliminating the need for an external startup network.
